--- Comment #3 from Maxim Kuvyrkov <mkuvyrkov at gcc dot gnu.org> --- Hi Tom, I can't reproduce this. I'm trying "make check-gcc RUNTESTFLAGS="vect.exp"" on a native x86_64 bootstrap. What is required to trigger this? [FWIW, I see that code handling additional_source has different paths for remote vs local testing, so it might be triggered only with remote testing.]
