#18963 [Fbk->Opn]: Reproducable crash with simple string functions.

ID: 18963 User updated by: si@darkness.nu Reported By: si@darkness.nu -Status: Feedback +Status: Open Bug Type: Scripting Engine problem Operating System: IRIX64 6.5.16f IP25 PHP Version: 4.3.0-dev New Comment: I didn't have any problems compiling 4.2.2 or 4.2.1, just the latest snap version gave the problems. It was easily resolved by putting some full paths in. Previous Comments: ------------------------------------------------------------------------ [2002-08-20 23:09:34] kalowsky@php.net Sounds very suspicious of a bad install of Apache on the headers part. ------------------------------------------------------------------------ [2002-08-20 23:02:28] si@darkness.nu I had problems with a number of apache includes, I had to edit some headers and put in the explicit paths, it didn't seem able to find the proper paths for some headers "os.h, ap_*.h, etc" ------------------------------------------------------------------------ [2002-08-20 22:12:16] kalowsky@php.net what sort of problems did you have compiling this? Also updating version ------------------------------------------------------------------------ [2002-08-20 10:21:59] si@darkness.nu A note from another IRIX admin who looked at this problem: I note that the problemic address is not null. It resembles a stack address. In that case, the most frequent cause of the problem is a miscoded procedure that is called and it returns the address of a variable with is on the stack and that stack frame is then released. If the stack shortens by enough, then the address may become invalid as the kernel releases under some circumstances unneeded stack frames. Randolph J.
