It appears that there was no effort made to reset the counters at all.
If a parser run finished with one of the counters active, it would
remain active for the next run.  Then if the memory address of an element
assigned to a counter happened to be reused, by pure chance, the counter
would appear to refer to the new element, incorrectly.  This bug (possibly
only in the test suite, not in "real" runs of the program) has likely
always been present (since I wrote the original code for parsetexi);
the recently added test only allowed the bug to surface.

I've committed a fix in commit 23da32ceb93ef7495 (2024-02-25).
