I could reproduce it as follows with pristine gcc 3.4-branch:

[gb@n2 gcc]$ ./xgcc -v
Using built-in specs.
Configured with: ../configure --enable-shared --enable-threads=posix 
--disable-checking --enable-long-long --enable-__cxa_atexit 
--enable-clocale=gnu --disable-libunwind-exceptions 
--enable-languages=c,c++ --host=i586-pc-linux-gnu
Thread model: posix
gcc version 3.4.2 20040812 (prerelease)

[gb@n2 gcc]$ ./g++ -B $PWD  ~/vrac/exceptions.cpp -L  
../i586-pc-linux-gnu/libstdc++-v3/src/.libs -O2 -fomit-frame-pointer
[gb@n2 gcc]$ ./a.out
Segmentation fault

with --host=i686-pc-linux-gnu, his testcase passes.
