On Perl 5.19.7 and 5.19.8, HTML-FormHandler-0.40055 is failing its tests
for me, with memory-related problems. I've seen this on 5.19.7:

t/fields/repeatable.t ................... 1/? perl: malloc.c:4538: _int_malloc: Assertion `victim->fd_nextsize->bk_nextsize == victim' failed.
t/fields/repeatable.t ................... All 3 subtests passed

And these two failure modes on 5.19.8:

t/fields/repeatable.t ................... 1/? perl: malloc.c:4636: _int_malloc: Assertion `victim->fd_nextsize->bk_nextsize == victim' failed.
t/fields/repeatable.t ................... All 2 subtests passed

panic: attempt to copy freed scalar 9a07b7c to 9bc935c at /opt/perl-5.19.8/lib/site_perl/5.19.8/i686-linux-64int-ld/Class/MOP/Method/Wrapped.pm line 163.
# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 255 just after 2.
Attempt to free unreferenced scalar: SV 0x9a07b7c during global destruction.
t/fields/repeatable.t ...................
Dubious, test returned 255 (wstat 65280, 0xff00)
All 2 subtests passed

5.19.7 introduced a memory bug, which was noted to affect
Test-Without-Module [perl #120657]. I initially thought HTML-FormHandler
was a victim of the same bug. But that bug was supposedly fixed in
5.19.8, and Test-Without-Module duly works again, but HTML-FormHandler
is still broken. It could be a bug in HTML-FormHandler, a different
core bug, or the same core bug having not been properly fixed.

According to ticket #120626, this was caused by v5.19.6-22-gebdc880.
I cannot reproduce this with current blead (v5.19.7-34-g4922547).
Is it still a problem on your computer?

I don't understand how that qualifies as "current blead". As I reported,
I encountered the problem with v5.19.8, hundreds of commits in the future
of v5.19.7-34-g4922547.

Is it still a problem on your computer?

What comparison are you trying to make?

Sorry. I copy and pasted the wrong thing. I have just re-confirmed
that it passes for me with v5.19.8-106-g6fbeaf2.

Fails for me with both v5.19.8 and v5.19.8-106-g6fbeaf2.

As mentioned in #120626, Data::Clone is at fault here. I have submitted a patch. I have also added mention of HTML::FormHandler to perl5200delta’s Known Problems section, in commit 67fc615.

With your patch to Data::Clone, valgrind reports t/fields/repeatable.t
is clean, and it passes. Thanks!
