If it is well reproducible, then a data breakpoint should work fine. 
Note that hardware data breakpoints are max 4 or 8 bytes, so you will 
need to figure out the exact address in the memory which will be 
illegally modified, and put a data breakpoint on it.

Last time I used PHP as an in-process library, it wrote over some random 
foreign memory when initializing itself. It was a bit tricky to cope 
with as I was not able to compile its sources any more :-S
