ImageMagick SEGFAULTs reading PNG

[ruibm]

ImageMagick crashes in release mode and asserts in debug mode when trying to read a corrupt PNG.
This is the assert:

Code: Select all

Assertion failed: (quantum_info->signature == MagickSignature), 
function DestroyQuantumInfo, file magick/quantum.c, line 215.

Is there any workaround to check whether an image is corrupt or not?

Post a URL to your PNG so we can download and inspect it. Thanks.

So the image is kind of personal, that's why I didn't publish it in the first place. When opening it on Gimp it does tell me that it is corrupted but it's still able to load it. I'll do a bit of debugging in the imagemagick code to see if I can pin down what the problem is. (if I find some other png that's corrupted I'll stick it online)

Thanks,
rui

We have a patch in ImageMagick 6.5.5-7 to fix the problem you reported. It will be available by sometime tomorrow.

Cool, that's mighty fast! I'll have a crack at it next week then, thanks!

Where can I get the patch?
And I've tried 6.5.6 and the bug is still there.
I use c++ interface and the image's url is
