Not obvious, but I see from the comments that people seem to be on the right
track.  Some target-specific thing under the hood (not obvious to me in the
source) in tree-ssanames.c provoking this?

FWIW, this problem did not manifest on neither ppc64le, x86_64 nor aarch64,
same source. (All *-linux.)
