I do not know how to reproduce this bug with less code at the moment.
Furthermode, the source is not open thus I cannot post it here. But I can help
to debug this problem if someone can tell me where I should look at. May be
related to PR65380.

It might be that this bug is a duplicate of pr/65559.
Could you please check if with current trunk (or 5-branch) problem still
exists?

same. I am still getting the following error when linking all together:

--- Comment #6 from Daniel Vollmer <zerolo at gmail dot com> ---
I'm seeing the same ICE in GCC 5.2.0 for x86_64 on Darwin. Unfortunately I
cannot provide the code in question (C++11, heavy template usage, computational
simulation code) and was unable to reduce the problem. I seem to recall that
the code (or at least a slightly earlier version of it) compiled fine with LTO
with 4.9.

Disabling partitioning with "-flto-partition=none" works around the ICE.

The link invocation is
g++-5 -v -flto -g -fopenmp -dynamiclib -Wl,-compatibility_version,1
-Wl,-current_version,1 src/SpatialDiscretization/DiscretizationFactory.cpp.5.o
src/SpatialDiscretization/Instantiations.cpp.5.o

-lxml2 -lnetcdf -lhdf5_hl -lhdf5 -lcgns -lutparmetis -lutmetis -lutgklib
-lzoltan -lmpi

The reported error is
lto1: internal compiler error: in add_symbol_to_partition_1, at
lto/lto-partition.c:211

lto1: internal compiler error: Abort trap: 6
g++-5: internal compiler error: Abort trap: 6 (program lto1)
