Looks that way. The stack trace doesn't seem completely trustworthy,
though, so you might want to consider recompiling with --enable-debug.

Note that you seem to be inside a re-entrant use of pltcl (outer
function is triggering a trigger also written in pltcl). I'm wondering
if your tuptable hacking is not taking account of the possibility of
re-entrancy. This might be a bug that had been latent in pltcl all
along, and was only exposed when you tried to free stuff ...
