            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:
