[Bug other/43085] New: Make profiledbootstrap fails with cc1plus catching SIGSEGV

[aanisimov at inbox dot ru]

I configured GCC rev. 156770 with the following options:

../gcc/configure --prefix=/home/artem/testing/gcc45 --enable-shared
--enable-bootstrap --enable-languages=c,c++ --enable-threads=posix
--enable-checking=release --with-system-zlib --disable-libunwind-exceptions
--enable-__cxa_atexit --enable-libssp --with-gnu-ld --with-lto --disable-nls
--verbose --with-arch=i686 --target=i686-slackware-linux
--build=i686-slackware-linux --host=i686-slackware-linux

With this configuration 'make' completes successfully, but 'make
profiledbootstrap' fails.

The last command which gets executed is

------- Comment #2 from fierevere at mail dot ru  2010-05-12 07:05 -------
Please change:

component to bootstrap
Host/Target and Build to i686-pc-linux-gnu
set higher priority and severity, this problem makes profiledbootstrap make
target unable to build and FDO-built GCC unusable, its definitely not "normal"
severity and not really a P3 prio !

Tested on current rev 159302 from svn branches/gcc-4_5-branch

I can confirm this with 20100902 from the 4.5 branch. the profiled bootstrap

With seeing .clone in fn names I suppose this is ipa-cp or ipa-sra.

I'm seeing this problem with r172238 on i686.  See:

http://builds.linaro.org/toolchain/gcc-4.5+svn172238%5Eprofiled/logs/i686-lucid-cbuild109-scorpius-profiled/

4.6.0 is fine.

I have found that reverting r167492  [1] fixes the problem for me. Of course it
brings back PR46806 but at least it should give a hint where the problem is.

Attaching the change as a patch, in case anyone is interested.

I can also reproduce the problem. It was not there with 4.5.1, came with 4.5.2.
When I force -O1 profiledbootstrap works fine, but ICE occurs with -O2.

And it fails for me even when I switch both IPA-SRA and IPA-CP off.
So at the moment I have reasons to believe the bug is not in any of my
areas of knowledge or interest.  And since there are bugs like that,
I'll leave this one to others.

I've tried make profiledebootstrap with IPA-SRA disabled (directly in the code)
and it segfaulted anyway.  Will try it with disabled IPA-CP tonight.

  I know about this trick and did a -j1 build :). Anyway, thanks for pointing
this out.

> Does adding "-Wcoverage-mismatch -fprofile-correction" flags help the issue?

  Where do these go?

(In reply to comment #8)

Artem, did you tried to make concurrent build ( make -j2 or anything more than
-j1 ) ?

there shouldnt be any collisions when building with single task (make -j1)

Does adding "-Wcoverage-mismatch -fprofile-correction" flags help the issue?

Right, I tried again and with "release" checking I get a segfault too.  I'll
examine this closer.

 It's interesting to note that profiledbootstrap break amd64 build too, though
for different reason:

../../gcc-current/gcc/c-parser.c:4672:19: error: 'incr' may be used
uninitialized in this function [-Werror=uninitialized]
cc1: all warnings being treated as errors

  For amd64 I configured with these settings:

../gcc-current/configure --prefix=/home/artem/testing/gcc46 --enable-shared
--enable-bootstrap --enable-languages=c,c++ --enable-threads=posix
--enable-checking=release --with-system-zlib --disable-libunwind-exceptions

--build=x86_64-slackware-linux --host=x86_64-slackware-linux --disable-multilib
--enable-checking=release

  Doing normal (not profiled) build with these settings succeeds for me.

 Doing profiledbootstrap with r165350 gives the following error (configuration
options are the same as in the initial report):

 I tried running compilation twice and always had this result.

I have run 'make profiledbootstrap' of today's checkout of the 4.5
branc (revision 165315) on i686 and it finished without any problems
for me.  I believe I configured it much like it is in the summary,
except that I used "yes" checking.

Can you please check whether the problem persists for you on the
current branch?  Thanks.
