             Bug #: 56963
           Summary: GCC 4.8.0 LTO issue: lto1: internal compiler error: in
                    add_symbol_to_partition, at lto/lto-partition.c:284
    Classification: Unclassified
           Product: gcc
           Version: lto
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: vhaisman@gmail.com


I have tried to compile log4cplus (C++ logging library) on Cygwin64
with -flto GCC option. I am getting the following failure:

lto1: internal compiler error: in add_symbol_to_partition, at
lto/lto-partition.c:284

Here is a link to archive with the minimal amount of .o files and a test.sh
script that reproduce the problem for me.

None of the tricks (-fno-reorder-blocks, -r, -nostdlib) help here. It still
fails the same way.

This has happened now, so the patch is good to go.

Thanks.

Richi was right.  The proper fix is to not ignore by_ref.

--- Comment #5 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
http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction#Reducing_LTO_bugs

(In reply to Václav Zeman from comment #7)
> Created attachment 32422 [details]
> preprocessed source

Works for me with GCC 4.9 on x86-64-gnu-linux with both -fuse-linker-plugin and
-fno-use-linker-plugin and "g++ -O3 -std=c++11 -w -r -nostdlib -flto". I
haven't tried 4.8, though.

[I had to replace "std::size_t" by "unsigned long" for the new operator in
order to make it compile.]
