If you run the program under the debugger, it should stop at the point of the error (sometimes you may need to look at earlier stack frames to see your code For example, if I allocate memory with malloc and I allocate 0x1000000 bytes (sixteen million bytes) then I might get an address like 0x01c90040 (ending at 0x02c9003F). Thanks Mike_2000_17 for your really detailed reply. Your address is pretty close to where the heap would put a big memory block of that size.
