--- Comment #1 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Yeah, I noticed such failures too.
AFAI researched them, they are related to out-of-stack issues.

The problem seems to be that within lto a lot of vec-s are passed on stack and
lead for stack-limited targets easily to out-of-stack issues.

Not sure if this is here really the reason, but my gut feeling would say so.

Nevertheless I can confirm this ice
