I have installed Testlink tool (not important what it is at the moment 
) using Apache (2.2.22), MySQL (5.0.67), PHP (5.3.16). After sending an form to server I get blank page on the screen and entry in error_log file similar to:
[Wed Oct 17 15:24:27 2012] [notice] child pid 18481 exit signal Bus error (10)
There is no core file generated so I does not know even how to debug it. Do you have any suggestions? Please, help me
