Previous Comments: ------------------------------------------------------------------------ [2012-08-26 05:54:15] ras...@php.net There is no changelog entry for it. Your report is not specific enough, but we need to know if it is happening in a current version before we bother spending any time looking for it. chasing fixed bugs isn't the best use of our time. ------------------------------------------------------------------------ [2012-08-26 05:26:02] sergiu dot ionescu at gmail dot com Can you please point me to the change-log note for this fix? I want to be 100% sure that it's the same issue, as we are trying to be as conservative as possible with environment updates. Thanks! ------------------------------------------------------------------------ [2012-08-25 17:42:42] ras...@php.net Ah, I see the version at the bottom of your report now. I have fixed it in the report. 5.3.2 is from March 2010. Please upgrade to something more recent. ------------------------------------------------------------------------ [2012-08-25 17:41:00] ras...@php.net The PHP version is not irrelevant at all. We can't possibly do anything with this bug unless you tell us which version you are seeing it in. ------------------------------------------------------------------------ [2012-08-25 17:33:11] sergiu dot ionescu at gmail dot com Description: ------------ I randomly get segmentation faults while running cli scripts. The fault occurs at the end of the script run and happens in more than 50% of the cases. Expected result: ---------------- No seg fault.
