Bug ID: 59187 Summary: internal error with -O2 Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: alessio211734 at yahoo dot it Hi, I get a internal error when compiling with MinGw 4.8.0. I attach the preprocess file where I get the error. The flags in the makefile: CC = gcc CXX = g++ DEFINES = -DUNICODE -DQT_LARGEFILE_SUPPORT -D_DENTALCAD_PRO_MACRO_ -DNOMINMAX -DNDEBUG -DQT_DLL -DQT_NO_DEBUG -DQT_XML_LIB -DQT_OPENGL_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN CFLAGS = -O2 -Wall $(DEFINES) CXXFLAGS = -fpermissive -save-temps -O2 -frtti -fexceptions -mthreads -Wall $(DEFINES) I have compiled my code in ubuntu with gcc 4.8.1 and compile correctly in release. In windows fails with mingw 4.8.0 e mingw 4.8.1. I saw that if I use the flag -O1 compile while with -O2 I get the error.
