--- Comment #6 from John Buddery <jvb at cyberscience dot com> ---
I had this issue as well, and here is the solution I used in case anyone is
still interested. I believe it is caused by an HP-UX linker bug, the same one
described by this comment and workaround  in config/ia64/hpux.h:

  /* The HP-UX linker has a bug that causes calls from functions in
   .text.unlikely to functions in .text to cause a segfault.  Until
   it is fixed, prevent code from being put into .text.unlikely or
   .text.hot.  */

  #define TARGET_ASM_FUNCTION_SECTION ia64_hpux_function_section

While this workaround is sufficient for C code, unfortunately g++ can use
multiple text sections for various different reasons when compiling c++ code
(lookup Vague Linkage for details).

This means g++ is broken on HP ia64, and gcc 4.8.0 build using g++, which is
why the bootstrap now fails.

The workaround I applied was to add the line:

   #undef MAKE_DECL_ONE_ONLY

to gcc/config/ia64/hpux.h, below the lines I referenced above. This seems to
prevent gcc from using .linkonce.t sections, and keeps the HP-UX linker happy.
I've no idea if this is the correct solution, but it does produce a working
g++.

Unfortunately just applying this edit you your 4.9.2 sources and building isn't
good enough, because it's your existing broken g++ which does the stage1 build. 

As far as I can tell all g++ versions available for download are broken, so you
have to first download and build 4.7.4 or earlier, applying the same 
gcc/config/ia64/hpux.h as above. This version builds with gcc, not g++, so the
bootstrap isn't a problem. Once you have a fixed 4.7.4 g++, you can then use
that to bootstrap 4.9.2 - after again apply the hpux.h edit to the 4.9.2
sources.

In my case when building 4.9.2 I also had to disable libgomp, but I think
that's a different issue.

Of course a much better solution to all this would be to get a fixed HP linker;
but I can't even tell if any of the HP patches help as they don't seem to make
these fixes generally available.

--- Comment #7 from Alexander <alm at sibmail dot ru> ---
I try to boostrap gcc as recommended by John Buddery 2015-04-27 09:55:36 UTC
but libcpp/charset.c was produse ICE

configuration:

../gcc-5.2.0/configure \
--enable-languages=c,c++ --prefix=/opt/hp-gcc \
--with-local-prefix=/opt/hp-gcc --with-gnu-as \
--with-as=/usr/local/bin/as --without-gnu-ld --with-ld=/usr/ccs/bin/ld \
--disable-nls --disable-libgcj --enable-shared --enable-threads=posix    \
SED=/usr/local/bin/sed SHELL=/usr/bin/bash


Building libcpp/charset.c with -O1 was OK.
Now I file bug for it.

--- Comment #9 from John Buddery <jvb at cyberscience dot com> ---
I should clarify that the workaround above only works fully on 4.9.2 and
earlier.

>From 5.0 onwards, gcc seems to have a problem building 32 bit code for
ia64-hpux.
It doesn't emit intstructions to properly set the top two bits of pointers
after widening, which is required because of the way ia64 segments it's address
space.

So, you might have better luck with 4.9.2. Or, you might be able to build gcc
as a 64 bit executable (though I don't know how to do configure it this way).

--- Comment #10 from Alexander <alm at sibmail dot ru> ---
Have you try to examine core (dwarf-4) produced with this gcc configuration?
Trying this has no luck with gdb-7.x (it is not working at all)
One solution for me is a globally fallback to dwarf-2 (and use gdb 6.3).

I tried to use the work around suggested by John but was not succesful in
making the 4.9.2 compilation. I applied the patch to the 4.7.4 and made a
succesful build of 4.7.4. I then installed the 4.7.4 and used to compile 4.9.2
which run into the below error:

So it assumes the build has gone much further ahead but it failed with the
libstc++ compilation.

The configure command which I used is:

../gcc-4.9.2/configure --prefix=/opt/gcc_492 --with-local-prefix=/opt/hgcc_492
--with-gnu-as --with-as=/usr/local/bin/as --without-gnu-ld

--enable-threads=posix --enable-languages=c,c++ SED=/usr/local/bin/sed CC="gcc
-mlp64" CXX="g++ -mlp64"

Unfortunetly, gcc for HPUX is a still 32-bit toolchain, sou should build it by 
default 32bit options (without -mlp64)

Yes. i also tried without the mlp64 option both for building the 4.7.4 and also
for building the 4.9.2 using the 4.7.4 but again I have the same issue. Means.
* 4.7.4 build is successful.
* 4.9.2 build fails at libstdc++-v3 as below.

The reason I went with using the mpl64 option was with out that option when I
was doing a 4.9.2 building using the GCC 4.2.3 which was available by default I
was getting the linker issue which is specified in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61577. The only way I got get pass
the linker errro just after the libbackend.a creation was using the -mlp64
option for 4.9.2 build.

Were you successful in making the 4.9.2 build?

--- Comment #14 from John Buddery <jvb at cyberscience dot com> ---
I did get a working 4.9.2 build, with the workaround from my earlier comment.

It's a 32 bit build, bootstrapped with the hp 4.6.2 gcc distribution, my config
line was:

  $ ../gcc-4.9.2/configure --disable-libgomp --with-as=/opt/hp-gcc/bin/as
--enable-languages=c,c++ --prefix=/usr/local/gcc-4.9.2
--with-gmp=/usr/local/gcc-4.9.2 --with-mpc=/usr/local/gcc-4.9.2
--with-mpfr=/usr/local/gcc-4.9.2

I don't remember any errors in libstdc++. I would recommend installing gawk if
you haven't already - the HP awk can cause issues when building gcc.

It has been 2 years, does this still happen?
