The README file for HTML::Parser says to report bugs to this mailing
list.
I have tried using HTML::Parser in a threaded application. If an
HTML::Parser object exists when there is more than one thread, it has
problems destroying the object afterwards (and the program dies).
Here are a few one-liners (and their output) that demonstrate the
problem:
$ perl -MHTML::Parser -Mthreads -e'(async{new HTML::Parser})->join'
Bad signature in parser state object at 3767c0.
Unbalanced string table refcount: (1) for "_hparser_xs_state" during
global destruction.
Scalars leaked: 4
$ perl -MHTML::Parser -Mthreads -e'$p=new HTML::Parser; (async{})->join'
Scalars leaked: -13
Bad signature in parser state object at 62ccd0 during global
destruction.
But if I destroy my HTML::Parser object before creating a thread,
there is no problem:
$ perl -MHTML::Parser -Mthreads -le'$p=new HTML::Parser; undef $p;
(async{})->join; print "ok"'
ok
I hope this is helpful. I'm afraid know almost nothing about C and
XS, so I can't be of any more help.

P.S.: I am using threads.pm version 1.57 and HTML::Parser version 3.55.
