I tested the repro script PID1080 from 60771 that produces a >8k text file and tries to require it. I also produced another >8k file myself and added some php code to it (inside <? php tags) and required it from another script. With 48034 patch, that also works." phpt for that is coming too Previous Comments: ------------------------------------------------------------------------ [2012-01-16 17:09:02] pvasilevich at parallels dot com I have applied similar patch and problem solved.
