After seeking advice on the best way to submit patches, I've made a diff -dpu patch of swf.c and posted it at http://people.jtlnet.com/~adam/phpbug-32538/swf.c.patch

Thank you for the report, and for helping us make PHP better.

And you really should use anything else than this extension..
for example ext/ming
