PS: how do I re-open this bug? Previous Comments: ------------------------------------------------------------------------ [2005-03-09 23:11:50] ericvanblokland at gmail dot com I've experienced this bug with latest stable php5 release. However, I do not believe the gif is corrupted, just odd formated (which you may very well call corrupt if you like). Due to the fact most programs just read these gifs whatsoever, as well as create them, our "stupid" customers will continue using them. Would be nice to be able to work with them or rejecting them without timeing out the script. ------------------------------------------------------------------------ [2005-01-22 01:00:08] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

The above command causes it to hang. Tracing through the code using a debugger it does look a lot like an infinate loop, though it could just be a really long one. I believe the infinate loop starts at line 155 in gd_gif_in.c at for (;;) { - I think it may just not be reaching an exit condition. I may investigate more later. Very strangely, if I download the gif and run the same command without going to the site at runtime, there is no such problem.
