Hm, so I got around to check this out again and in fact the same happens
with today's svn version:

examples/step-14> c++ -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --prefix=/tmp/bangerth/bin/gcc-mainline
--with-mpfr=/tmp/bangerth/bin --with-gmp=/tmp/bangerth/bin --disable-multilib
--enable-languages=c,c++
Thread model: posix
gcc version 4.3.0 20071212 (experimental) (GCC) 

examples/step-14> c++ -D_GLIBCXX_PARALLEL -fopenmp -march=native -mtune=native
a.cc -g -O2

examples/step-14> ./a.out 
Segmentation fault

examples/step-14> uname -a
Linux bloc640b 2.6.22.9-0.4-default #1 SMP 2007/10/05 21:32:04 UTC i686 i686
i386 GNU/Linux

This is with the program posted before, with pretty much the same backtrace. 
Johannes, does the program work for you?

Best
 Wolfgang
