Quick question on memory access violations

[blahz0rz]

When you normally run a file it runs fine..but sometimes when you load them in to olly you get things such as memory access viloations..why is this?

[AndreaGeddon]

programs may make normal access violations, for example if they use a pointer to access memory regions they could set up a tray-catch block to see if the pointer is valid or not. With your debugger you should be transparent to such exceptions, they are handled by the program.

access violations are usually thrown up when you dont have permisions to read/write/execute the memory page you address. usually a corrupt pointer can throw this up pointing to memory that hasnt the required security discriptor
