Hi,

I encountered a memory leak in the coders/jp2.c. I had sent a mail to the imagemagick-bugs mailing list. I was asked to report it here.

Here is the patch for the memory leak. This affects all versions (trunk and stable).

Code: Select all

Index: coders/jp2.c

Thanks for the problem report and patch. We'll get the patch into ImageMagick 6.7.4-3 Beta by sometime tomorrow.

Thanks for your reply. I am wondering if the Windows binary package will be updated with the memory leak fix.

Yes, when ImageMagick 6.7.4-3 is release within a few weeks.
