Bug 277628 – dev-libs/apr-1.3.6 cause segfaults when it was built with newer kernel headers than currently used kernel

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ruslan U. Zakirov 2009-07-13 10:12:03 UTC]

apr-1.3.6 cause seg fault when a child starts. Seg fault happens in apr_pollset_add. I don't have full backtrace cuz downgraded quickly. Did a little bit research on the subject and looks like it may be related to epoll limit, but I'm on linux 2.6.26 and it shouldn't be affected.

Feel free to request more info if needed.

Reproducible: Always

Steps to Reproduce:
1. configure apache for perfork
2. start in -X mode


Actual Results:  
segfault

Expected Results:  
functional one process server

Downgrading to 1.3.5 fixes it.

I'd say better mask for now, we'll trash more boxes otherwise....

[Comment 5 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2009-07-21 17:07:08 UTC]

dev-libs/apr-1.3.7 will be released most likely in this week and it should fix this bug.

[Comment 6 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2009-07-24 22:10:20 UTC]

Fixed in dev-libs/apr-1.3.7.
