I tried to build the current gcc-4.5.0 svn (rev. 151902) It now failes for a few days with a segfault.
It happends if the ./gcc/xgcc is used, the broken down command is now: LC_ALL=C gcc/xgcc -Bgcc -g -O2 -c gcc/libgcc2.i ./gcc/libgcc2.c: In function '__powixf2': ./gcc/libgcc2.c:1739:1: internal compiler error: Segmentation fault Removing any other parameters will not trigger the segfault. The normal CFLAGS are "-march=opteron -O2". The gcc used to compile is a 4.3.2. -- Summary: Segfault while build Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: m4rkusxxl at web dot de http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41417
