Comment on attachment 139617 [details] Patch Do we have an image we can test this with? It seems if we keep maintaining a PNG decoder (which we really *don't* want to do as a project), we will need to come up with a testing harness and a corpus of a bunch of broken png files. :(

No, no test image sorry. Agree we need to come up with a better test suite.

So it's impractical to test this with our current technology, but the plan is to move towards using pngsuite for testing our decoder, which should catch issues like this one. http://www.schaik.com/pngsuite
