             Bug #: 53407
           Summary: ICE compiling pcre-8.21 in
                    function_and_variable_visibility, at ipa.c:1002
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rainer-gccbugs@7val.com


g++ throws an ICE when linking pcre-8.21 with -flto, it works with -O3. Since
the bug is in the linker phase, I don't have any preprocessed files I could
attach. The pcre source code is available at
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ If required, I can
supply the entire source directory, including the object files used in the link
line below, or any subset thereof.

The GCC used is the default Version included in Ubuntu 12.04 x86_64.
