Hi Hans,

Thanks for trying it.

I cannot reproduce it following your script.  BTW, I believe the
mkdir is useless, and ./configure would suffice: you seem to build
in place.

Given the nature of the messages:

I wonder if you did not have say two "make check" running concurrently?
Maybe one of them, for some unknown reason, rewrote "testsuite" while
the other one was running it?

What's the result of "wc tests/testsuite"?  I have

  164175  551986 5095566 tests/testsuite

If that's not the error, I would need something more deterministic to
reproduce it, e.g., some modification of the hans.sh script I attached,
that shows the error.
