Without knowing more about your situation I can only suggest a few general things... make sure you have a valid stack for that function (or avoid all stack operations in the function), that your interrupts are disabled, and that any vectors in the system vector table don't point to code that goes away when you erase flash. Lastly, make sure your function is linked to run at the address you put it... the code may not be relocatable and may jump to a spot in is old location.
