I just tried 5.20.3.
For my issue (mentioned earlier in this thread), 5.20.3 does not help.
I'll post a followup message in anew thread when I have time, but
basically, I started seeing two different problems somewhere between
5.19.0 and and 5.20.0:
1) "panic: attempt to copy freed scalar xxxx to yyyy" reliably
reproduced when calling $cgi->param(x => ''); inside a TryCatch try { }
block. (and $cgi is CGI.pm here)
Test case I have works perfectly against perl, but produces the above
panic under mod_perl.
Seems to be something to do with TryCatch or Devel::Declare as the
problem goes away if I use eval { } instead of try { }. Unfortunately
this is a large client codebase heavly invested in TryCatch so moving
away from that is not going to be fun/easy.
2) repeatable segfault by a certain subroutine doing something as simple as:
sub foo {
my ($self, $field, $type) = @_;
if ($type = 'X') {
return $self->_bar($field);
}
}
The fun part of this one is that if I remove the "return" keyword, the
segfault goes away.
