This is why I wondered in the original patch message:

If I understand correctly, thisjob == -1 means there is no foreground
job. I'm scratching my head over how list_pipe can be true when there
is no job in the foreground. Could you please run
ZTST_verbose=2 make TESTNUM=B03 check
to verify which test is causing the segmentation fault? I suspect it's
the very last test with "print -lO ... | while read ..." but I'd like
to be sure. (OTOH it may not be possible to reproduce the fault with
verbose output, but it's worth a try.)
I further suspect the signal is arriving during foo=$line[i] or some
other part of the inner loop where no actual command is being run, but
list_pipe remains true because of the outer loop.
