Re: [eAccelerator-developers] eA && PHP 5.1

[Hans R. <ha...@pa...>]

Hi Sönke,

See http://httpd.apache.org/dev/debugging.html

The way i do it is with gdb, running apache in single thread mode (run 
-X in gdb)

You will probably need to isolate your development/debugging work on a 
webserver that does not serve any other reqs at that time.

The segfault on restore problem is one of the problems i have remaining. 
Simple scripts work fine, even phpMyAdmin works, but complex class 
usage/OOP constructions still seem to fail on restore.

Could you please test if the problem persists with the optimizer turned off?

Thanks for your effort,

Hans
