Comment (by SimonKing):
It is really really REALLY frustrating. Volker's patchbot keeps reporting
a segfault, but I can not reproduce it on bsd.math, With #5457 and the new
GAP spkg, make ptest just reports a single error:
{{{
sage -t -force_lib "devel/sage/sage/interfaces/gap.py"

The following tests failed:
sage -t -force_lib "devel/sage/sage/interfaces/gap.py"
Total time for all tests: 29.7 seconds
}}}
That's rather strange, but I guess that's the problem of the GAP spkg.
In any case, I don't see a segfault. Not on my laptop, not on the machine
in my office, not on bsd.math.
