In article <7pvk33$ut4$1 AT nnrp1 DOT deja DOT com>, Sid <zidharta AT yahoo DOT com> writes >I made a bmp loader >it works fine but when the program quit Sid, the textbook suggestion for this is that you are probably deallocating some memory on exit, and have done a dodgy deallocation of a pointer e.g. one which has already been reallocated (or maybe just one which is corrupted). Cure the former case by setting pointers to NULL __immediately__ after deallocating them. I don't know whether it is possible to right a function which tests for an invalid pointer without bombing. You could then call it in key, but rarely visited, gateways such as destructors. -- ^-^-^-@@-^-;-^ http://www.xemu.demon.co.uk/ (..)__u news:alt.smoking.mooses
