how to break on a write to a specific mem location?

[maxmagna]

Hello.

What I need to do is this. I know the address of a specific memory location on the heap. I need to execute my program until for some reason there is an attempt to access and write (change the content) to that specific memory location.

 

I am trying to debug a bug that looks like memory corruption: the content of a memory location which should not change after start up is in reality altered. I want to find out the backtrace when that happens.

Any suggestions/pointers are appreciated. thanks.
