Bug #: 56927 Summary: 4.7.2 build ICEs when built with 4.8.0 and --disable-bootstrap Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassig...@gcc.gnu.org ReportedBy: seg...@gcc.gnu.org Host: x86_64-linux Target: x86_64-linux Build: x86_64-linux When using a 4.8.0 host compiler and configuring with --disable-bootstrap, a build of 4.7.2 fails with /home/segher/src/gcc-4.7.2/libgcc/libgcc2.c: In function '__absvdi2': /home/segher/src/gcc-4.7.2/libgcc/libgcc2.c:273:1: internal compiler error: Segmentation fault There is no such error if the host compiler is 4.4 or 4.7, or without --disable-bootstrap; it does have the error if doing a cross to i386-elf. I haven't tested with tip-of-tree of either 4.7 or 4.8 or on different architectures.
