debug php-cgi.exe + vb6 dll

问题

I'm calling through php a vb6 .dll (IIS) and on some rare and weird occasions when i call a particular function the php-cgi.exe crashes with message:

the instruction 0x029b7387 referenced memory at "0x0f138000". The memory could not be written. Click OK to terminate, click cancel to debug

the memory address might slightly change but always ends in 8000.

Is there any way to debug and find out what is wrong with my .dll ?

thanks in advance.
