I think what you see should be PR99126 [1] that was fixed recently on
trunk.

IIRC (might be wrong) Eli is on a GCC 9, where at the time I could not
reproduce this bug.  If we discover PR99126 shows-up in versions other
than 10 we might want to relax the version check around the workaround
we have in place.
