Bug ID: 57368
Summary: Trying to build CilkPlus fails with an ICE
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: nmm1 at cam dot ac.uk
This is different from 56485. I have tried to report it to the CilkPlus
team, but the mechanism appears to be broken. I haven't tried stripping
the problem down, as that is a lot of effort and it is worth finding out
how best to proceed first. It fails with at least 4.6.2 and 4.8.0 in
the same place. This is a reasonably modern 16-core AMD running OpenSUSE
12.1. The download is:
svn co svn://gcc.gnu.org/svn/gcc/branches/cilkplus
The build script is:
../configure --prefix=/home/nmm/CilkPlus --disable-bootstrap \
--enable-languages=c,c++,fortran \
--enable-werror=yes --enable-checking=all --disable-decimal-float
make
I shall retry without --enable-checking=all, but I typically work with
all checks on :-) If particular information would be useful, please
tell me what.
The diagnostics are:
/bin/sh ./libtool --tag=CC --mode=compile
