Hi, The following small program gives ICE when compiled like this: g++ -Wall -fopenmp -O2 -I$POLDEST/ext/include -E -o./test_pp.cc ./test.cc g++ -Wall -fopenmp -O2 -L$POLDEST/ext/lib -o./test ./test_pp.cc -lblitz -lgomp ./test.cc: In function ‘int main()’: ./test.cc:3: internal compiler error: Segmentation fault When removing the 'try-catch'-part it works fine. ---- #include <blitz/array.h> int main() { try { blitz::Array<float,1> transOrig( 10); blitz::Array<float,1> trans( 10); blitz::Range myRange( 0, 9); #pragma omp parallel for for( int i = 0; i < 2; ++i) { trans += transOrig( myRange); } } catch( std::exception) {} } Here the preprocessed source: http://data.marssoft.de/attachment-bug-gcc.bz2 And my specs: ~> gcc -v Using built-in specs. Target: x86_64-unknown-linux-gnu Configured with: [...]/gcc-4.2-branch/configure -v --enable-languages=c,c++,f95 --prefix=[...]/extgcc-x86_64_gcc4-r124295 --enable-shared --with-system-zlib --without-included-gettext --enable-threads=posix --enable-nls --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-debug --enable-gtk-cairo --with-mpfr=[...]/extgcc-x86_64_gcc4-r124295 --with-gmp=[...]/extgcc-x86_64_gcc4-r124295 --disable-werror --enable-checking=release --disable-multilib --enable-bootstrap Thread model: posix gcc version 4.2.0 20070430 (prerelease)
I can confirm the bug for i486-unknown-linux-gnu, too.
Testing a patch.
