--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
libgcj.so is not linked with libstdc++ (I think intentionally), and contains a
bunch of VLAs in there:

at least. I wonder why is r234966 apparently more aggressive than what 4.9 had
in, because I don't remember such issues in libgcj back then.
So, either we need to get rid of the VLAs and replace them say by alloca, or
have a way to disable this new stuff (which IMHO has been added way too late)
through command line option,
or need to link with libsupc++, or provide a stub for the symbol.
