Is today DST changeover where you live?
The time-related tests have always failed near DST boundaries; the
queries you mention effectively assume that the difference between
successive midnights is exactly 24 hours, which is wrong for DST days.

Ah. The parallel tests set up the postmaster's timezone to be PST8PDT.
Today is DST changeover in that zone, even if it isn't where you live.

Write it off as a broken compiler. Compiler segfaults on valid code are
not our problem. (As far as I know, the 2.8 series of gcc releases were
never robust enough for production use. Try 2.95.2 instead.)
