Topic: exit signal Segmentation fault in Apache after php update

I updated to the latest php 5.3.3 and after that my website returned blank pages.

There are no logged errors in php, only the following in apache error log:

[Thu Nov 04 03:59:49 2010] [notice] child pid 20902 exit signal Segmentation fault (11)

After some researching i pinpointed the problem to the memcache extension. If i disable this, seems to work, however my application needs it to function.

I tried to reinstall the latest php-pecl-memcache, and tried compiling it from source too. It produced the same error again.

I managed to resolve this by downgrading to php 5.3.2 from your repository, however it would be nice to be able to use the latest version.

Maybe anyone has a solution ?

Re: exit signal Segmentation fault in Apache after php update

I will try to reproduce.
Seems to be an upstream bug.

Can you try with php 5.3.4-dev  (in remi-test) to see if this issue is fixed there ?
