Please provide full configure command, svn revision and details of
bootstrap compiler.

This might a problem with thread model.  I always configure with
--enable-threads=posix.

I used the gcc-4.8-20120429 snapshot and the only configure option (besides
prefix and libraries) was --disable-libstdcxx-pch. The host I compiled on was
gcc61. I didn't know about the --enable-threads=posix, but I'm sure a year ago
I had bootstrapped without it.

It's not a problem with the thread model.

I can't duplicate the problem. I believe that this is because
I have a more recent version of libc6 installed (2.13-32) than
that on gcc61.

Please provide the preprocessed source for the failing command.

This appears to be a compatibility issue with old libc6 versions.

It appears to me that gcc61 is using the old linuxthreads
implementation of pthreads.  It may be necessary to use
__GTHREAD_MUTEX_INIT_FUNCTION instead of __GTHREAD_MUTEX_INIT,
etc, in ext/concurrence.h.

This needs to be looked at by a c++ maintainer.

Note however that NPTL is being used instead of linuxthreads.

I know parisc had switched to NPTL in Debian lenny.  It's possible to
update to unstable from lenny but it's a bit of work.

You might try configuring with "--disable-libstdcxx-threads".  It
disables C++11 threads support.

--disable-libstdcxx-threads doesn't help, I get the same error at exactly the
same point(guard.cc:33).

guard.cc is always built, it's part of libsupc++ so it's nothing to do with the
C++11 thread library.

I'm pretty sure we've already dealt with this failure elsewhere, IIRC the
linuxthreads pthread_mutex_t type has a volatile member causing the default
assignment operator to be deleted.

For PR 51296 I added a way to force use of __GTHREAD_MUTEX_INIT_FUNCTION, by
defining _GTHREAD_USE_MUTEX_INIT_FUNC in
libstdc++-v3/config/os/.../os_defines.h

We might want to put something in config/os/gnu-linux/os_defines.h so that the
macro is defined when using linuxthreads

I'm thinking a test needs to be added to GLIBCXX_CHECK_GTHREADS in 
acinclude.m4.

In the past we had faced a similar problem, I found the patch I think you had
given me (attached). Could give a solution but doesn't apply cleanly now.

I think gthr-posix.h in libgcc contains the overrides.  Could you  
check if providing
the suggested defines in the libstdc++  linux os_defines.h resolves  
the issue?

If that works, it's just a matter of how to detect linuxthreads and  
provide the defines.

Defining _GTHREAD_USE_MUTEX_INIT_FUNC in os/gnu-linx/os_defines.h didn't help.
See attached files for new error message and preprocessed source. 

Also keep in mind that gcc61 shows some strange message in its dmesg. Though
unlikely, it might be that some kernel or hardware bug is involved...

The new error is in the recursive mutex definition.  You also need to define

Thanks, I'll leave that to you then since it's no big priority for me. 

FYI defining _GTHREAD_USE_RECURSIVE_MUTEX_INIT_FUNC brought other problems. I'm
attaching related info for the sake of completeness.

The issue seems to be resolved with these 3 defines, thanks for helping. I now
get an ICE at a much later phase which is probably unrelated. I'll try some
more recent snapshot later and file a separate bug if it persists. The ICE is:

Probably, mpfr, gmp, binutils, etc need updating.

Bah, the patch on the 4.7 branch isn't right as it also disables the macros
when using NPTL, which isn't needed. As Dave suggested on comment 15 we'll need
to check in acinclude.m4 whether the macros cause problems. 

Proper fix coming soon ...
