gcc crashes with an ICE, when generating code with debugging information. if
the flag -g is omitted, the code compiles fine ...

gcc is invoked like this:
gcc-4.2 -v  -save-temps -DNDEBUG -D_PTHREADS -D_THREAD_SAFE -D_REENTRANT
-D_POSIX_SOURCE -march=i686 -O -Wfatal-errors -I../../Demo -I../../Source -g 
-c ../../Demo/TestHashTable.cpp
Using built-in specs.
