apache crashes during php zend debugging sessions

i am using eclipse with PDT with the zend debugger to test my website, however, it randomly says "Apache HTTP Server has encountered a problem and needs to close. We are sorry for the inconvenience."

here's the "Apache HTTP Server: Error signature"

szAppName : httpd.exe     szAppVer : 2.2.15.0     szModName : php5ts.dll     
szModVer : 5.2.13.13     offset : 0009a9ee     

Code (markup):

and the "Error Report Contents":

C:\DOCUME~1\xxx\LOCALS~1\Temp\WERd060.dir00\httpd.exe.mdmp
C:\DOCUME~1\xxx\LOCALS~1\Temp\WERd060.dir00\appcompat.txt

Code (markup):

what could this possibly be?

 

Any logs maybe?

 

yes, sorry. the [Zend Debugger] line is where it screws up:
