FYI, Poser keeps track of the low-water mark for each stack that it identifies. There's currently no way to extract that information (that is, there's no UI to report it and it's not logged anywhere when the application quits), but you could add that if you wanted. In the function SysHeadpatch::SysAppExit, look for where CheckForMemoryLeaks() is called. At that same location, you could report the information found in Poser's global variables gStackHigh, gStackLowWaterMark, gStackLowWarn, and gStackLow. You might also want to augment that reporting by taking a snapshot of the functions on the stack at the time that low-water mark was reached, so that you know what lead to that condition. I can point you to the appropriate routines to gather and print that information if you want.
