Re: autoconf test failures - how to react?

I suspect that your 'diff' program is buggy, and sometimes dumps core.
You might try substituting GNU diff.

That's an interesting diagnostic.  The shell reported a core dump,
but the test still succeeded.  Can you do this to find out more?

   cd tests
   ./testsuite -v -d 225

This I just sent you mail about already.

These seem to be failing for similar reasons: looking at the test logs,
it appears that 'diff' dumped core.  Can you reproduce the problem,
as follows?

cd tests/testsuite.dir/150
ls -l state-ls.before state-ls.after
file state-ls.before state-ls.after
diff -u state-ls.before state-ls.after
diff state-ls.before state-ls.after

and, similarly:

cd tests/testsuite.dir/222
ls -l state-ls.before state-ls.after
file state-ls.before state-ls.after
diff -u state-ls.before state-ls.after
diff state-ls.before state-ls.after
