I'm running the old examples/023_cjkfonts against PDF::API2 2.032 (just
released), on Win7. Every single page gets a message "Reference is
already weak at ...PDF/API2.pm line 1110." Line 1110 is
weaken $self->{'pagestack'}->[0];
in sub page(). My wild guess would be that the array reference
$self->{'pagestack'} only needs to be weakened once, and not every time
a new page is pushed on it. Does that sound reasonable? Is the ->[0]
making it apply only to the page just pushed, or is it something else?
Commenting out this line makes the program run without these warnings,
but I don't know if this is a safe fix or if there are other
interactions to be aware of.
I don't think I have seen this warning message anywhere else, either t
tests or other examples, so it may have something to do with the
specified CJK fonts themselves, or their supporting Perl files.
