Yesterday, I reported that the zdiff test for gzip-1.13.56-e549
failed on NetBSD 10.0.  Here is the tests/zdiff.log file:

To help debug that, could you please run the following commands in the 
gzip source directory and tell us the output?

echo a>a
echo b>b
./gzip a b
/bin/bash -x ./zdiff a.gz b.gz

I am assuming "zdiff" starts with "#!/bin/bash"; if it starts with 
something else please use that shell instead.

Thanks. I'm quoting it below. Apparently the equivalent of the following 
crashed:

echo b >b
gzip b
gzip_status=$(gzip -cdfq -- b.gz)

whereas the same thing succeeded if one substitutes "a" for "b". I 
suspect the problem isn't reproduced by the above commands, though, and 
don't know how to debug this further, remotely.
