libgfl heap corruption??
Posted: Thu Jun 11, 2009 10:19 pm
I wrote my own ActiveX wrapper around libgfl and for some time now (since v2.60 or earlier, but I might be mistaken a little) libgfl causes heap corruption every once in a while. Today I was lucky enough to "catch" such a crash. I'm currently using the latest version (from http://www.xnview.com/en/download_gfl.html).
I can't pinpoint what causes it exactly but it does. All I can do, because it happens in an IIS process, is dump a crashreport and hope someone figures this out. All I can say is that I've ruled out everything else and libgfl seems to be the culprit.
From what I understand from the crashreport is that this is caused by gflPNGSetComment but I'm sure I don't use that fuction (nor have I exposed it in my ActiveX wrapper). I have attached the crashreport and can only hope for the best. If you need any extra information I will do my best to provide it.
