Nor with gdb-14.2-release.

But now I can't reproduce it anymore with the original set of sources either.

So I guess at this point the only thing I know is that it happened 3 times, but
I have no reliable way of reproducing it.

Note that the test-case takes about 20 seconds, so a 100 iterations is already
about 30 minutes.

Reproduced once in run of 200 iterations.

Now reproduced with gdb 14.2 release tag, so I've confirmed that this is not an
issue due to the patches added in the package.
