I've been chasing down some weird panics in my CAM driver and have noticed that functions don't seem to save all register values before they modify them.
For example, function A uses register ecx to hold the value of a pointer. Part way through, function A calls function B which uses ecx as a loop index. The bad part is function B never saves/restores the value of ecx and function A starts dereferencing garbage. An informal sampling of my driver seems to indicate that ebx gets pushed/poped at entry/exit but ecx and edx don't. Does any of this sound familiar?
