             Bug #: 56775
           Summary: -flto and -fprofile-generate together result in a
                    link-time internal compiler error (in
                    "add_symbol_to_partition")
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: miles@gnu.org


If I compile my program with _both_ options "-flto" and "-fprofile-generate", I
get a link-time compile error.

Using either "-flto" or "-fprofile-generate" _separately_ seems to work
correctly.

Compiler version is:
g++ (Debian 20130316-1) 4.8.0 20130316 (experimental) [trunk revision 196694]

I'm not exactly sure how to cut this down...trivial test cases don't seem to
have the same problem.

A transcript of the final link (the options passed when compiling each object
file are similar, minus libraries etc):

We need a testcase.

--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
This PR might have the same reason as PR60567.

Namely, your GCC has not been compiled on a system with working linker plugin -
and thus, lto1 is not invoked with -fresolution=.

Try compiling with "-fuse-linker-plugin" - if that gives an error, try a GCC
which has been configured with --with-plugin-ld= pointing to a newer Binutils -
2.21 or newer. If that helps, it is a duplicate of PR60567.

If it doesn't help: Create a reduced test case as described at

Same spot of the ICE as 60567.
