Description:
------------
I had the same issue as http://bugs.php.net/bug.php?id=41612, but I found out the problem and the solution was simpler than that.

The file libgd00086.png in the /ext/gd/tests directory of the current php release is corrupted; on some systems, it sends the test performed in libgd00086.phpt in an endless loop, with libpng returning a CRC Warning on the file.

I do not know why this happens only on RHEL systems, but all I had to do to fix the issue was to replace libgd00086.png with a small png file I made.

The goal of this test (and its file) is to test this issue. Which is about not killing your box when one gives a corrupt PNG data, replacing the data with a valid png will not help :)

There is two problems to fix, one in php/gd (what I did) and two/three in libpng, what the last libpng releases did.

RHEL and debian, to list the two I know, did not update their system yet. But that's not our problem, sadly. No bug > bogus.

Oooops silly me. This was done on purpose, I suppose! Please close bug!

Hehe, thanks - you were faster than me! I hadn't read your reply yet :)

So basically we should wait for RHEL to issue a new libpng version?

Shouldn't RH have addressed this issued with https://rhn.redhat.com/errata/RHSA-2007-0356.html?
