OK, I have removed the free() before exit().

Hmm, it's a test case that fails with the current code and stops failing
with my fix, so I've put it there to show the problem. But, truly, it
does not bring much value after the fix is applied.

Attaching the new version, with the test case and free-before-exit
removed.
