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.
