When using -fopenmp, compiling my open source renderer ( http://users.softlab.ece.ntua.gr/~ttsiod/renderer.html ) triggers an internal compiler error. This did not happen with previous versions of GCC (I've added OpenMP support and seen it work fine since GCC 4.3.2). bash$ make ... g++ -DHAVE_CONFIG_H -I. -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -I./../lib3ds-1.3.0/ -fopenmp -O3 -g -Wall -Wextra -fomit-frame-pointer -ffast-math -funsafe-math-optimizations -mtune=native -msse -mrecip -mfpmath=sse -msse2 -mssse3 -DNDEBUG -MT renderer-Rasterizers.o -MD -MP -MF .deps/renderer-Rasterizers.Tpo -c -o renderer-Rasterizers.o `test -f 'Rasterizers.cc' || echo './'`Rasterizers.cc Rasterizers.cc: In member function 'void RasterizeScene<TriangleCarrier>::DrawTriangles(int, int) const': Rasterizers.cc:250:100: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. I attach the preprocessed output that easily reproduces the bug. With -fopenmp, the compiler crashes: bash$ g++ -c -fopenmp -O3 -g -Wall -Wextra -fomit-frame-pointer -ffast-math -funsafe-math-optimizations -mtune=native -msse -mrecip -mfpmath=sse -msse2 -mssse3 renderer-Rasterizers.i ...without it, it works: bash$ g++ -c -O3 -g -Wall -Wextra -fomit-frame-pointer -ffast-math -funsafe-math-optimizations -mtune=native -msse -mrecip -mfpmath=sse -msse2 -mssse3 renderer-Rasterizers.i Version of GCC (g++ -v): Using built-in specs.

The problem is that require_complete_type is just a nop if processing_template_decl, so we can't rely on the type being actually complete. ^ permalink raw reply [flat|nested] 6+ messages in thread
