--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
I can reproduce that on x86_64-linux-gnu and I'm trying to reduce that.

You can do that in the following steps:
1) reduce the number of objects needed on the linker command line - you can put
them to FILES.txt and then use cvise-delta to find a minimal set of files
needed; sometimes one needs to use -shared -fPIC in order to prevent missing
symbols linker errors
2) create pre-processed files for the culprit objects and then run gcc *.i
-flto ... and bisect all files at once with cvise
