Re: semi-panic: attempt to dup freed string?

Assuming for a moment that "marked free" does mean "who's reference count has dropped to zero", I'd really like to see how your code triggered the error. This wasn't pure Perl, was it?

This wasn't pure Perl, was it? No. It is a convoluted bit of XS code called from a convoluted Perl code, and only happens occasionally. and none-deterministically. Threading is involved. I'd really like to see how your code triggered the error. Me too. I could post everything but even if you got it to compile--it has windows specific calls--the chances of you being able to reproduce the circumstances are slim to none. If I knew what the error message meant, even if it doesn't allow me to fix it directly, it might allow me to produce a repeatable test scenario to demonstrate it. Besides which, asking what an error message means doesn't seem like such a bad or obscure thing to ask here? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]
