Comment(by zdeqb):

 This is a shot in the dark, but I was having crashes in perl signal
 handlers, until I changed the following lines in perl-
 handlers.c:perl_signal_cb

 {{{
 298         sv_args[i] = purple_perl_sv_from_vargs(values[i],
 299                                                (va_list*)&args,
 300                                                &copy_args[i]);
 }}}

 to

 {{{
 298         sv_args[i] = purple_perl_sv_from_vargs(values[i],
 299                                                args,
 300                                                &copy_args[i]);
 }}}

 This is on an x86_64. On an i386 the unmodified code works for me (and the
 modified causes bad thing to happen (tm)). Google says this has to do with
 va_list(s) being special...

 (I was about to file a bug report, but since this looked similar, I
 thought I'd comment before creating a new ticket...)
