SEGV building qt-3.3.3 with GCC 3.4.3 on RH 7.1/RHEL 2.1

[Albert Chin <gcc@mlists.thewrittenword.com>]

Just build Qt-3.3.3 with GCC 3.4.2 and 3.4.3 on Redhat Linux 7.1/x86
and RHEL 2.1/x86. No problems with 3.4.2. However, when building with
3.4.3, I get a segfault during the build:
  ...
  /opt/build/qt-x11-free-3.3.2/bin/uic -L
  /opt/build/qt-x11-free-3.3.2/plugins projectsettings.ui -i
  projectsettings.h -o projectsettings.cpp
  gmake[4]: *** [projectsettings.cpp] Segmentation fault (core dumped)

Trying to debug it (with gdb-6.3):
  $ cd /opt/build/qt-x11-free-3.3.3/tools/designer/plugins/cppeditor
  $ gdb /opt/build/qt-x11-free-3.3.2/bin/uic core
  gdb> bt
  #0  0x40e6c36c in ?? ()
  #1  0x40ce456b in exit (status=0) at exit.c:54
  #2  0x40ccf690 in __libc_start_main (main=0x8051550 <main>, argc=8, 
      ubp_av=0xbffed604, init=0x80501bc <_init>, fini=0x808bfa0 <_fini>, 
      rtld_fini=0x4000dda4 <_dl_fini>, stack_end=0xbffed5fc)
      at ../sysdeps/generic/libc-start.c:129
  #3  0x08051361 in _start ()

I tried adding print statements to main() but it didn't help. The last
statement in main() is 'return 0;' and everything works ok up until
this point. The SEGV appears _after_ the return statement.

gcc version 3.4.3 (TWW)

Both 3.4.2 and 3.4.3 are built against binutils-2.15 as/ld. According
to http://gcc.gnu.org/install/specific.html#*-*-linux*:
  Versions of libstdc++-v3 starting with 3.2.1 require bugfixes
  present in glibc 2.2.5 and later. More information is available
  in the libstdc++-v3 documentation.

From the libstdc++-v3 documentation, this requirement is for a locale
issue so I don't think it's the cause for the above problem.

Redhat Linux 9/x86, RHEL 3.0/x86, and RHEL 3.0/amd64 work fine. I
reviewed http://gcc.gnu.org/gcc-3.4/changes.html#3.4.3 but nothing
stands out as to what causes this. Where should I start looking?
