Hi, so, umm, what help are you asking for? :)
The chktsk goes down the stack and probes every page to make sure its accessible before it is actually overrun (I guess a costly measure to avoid stack overflows). I found its source code here: http://read.pudn.com/downloads63/sourcecode/embed/220997/FATFS/X86/ch kstk.asm__.htm So, it looks like the 66,000 is too much of a stack size. M$ says it is supposed to be 1MB, but I'm not sure what cegcc linker default's is. So I'd poke around the EXE file to see what it says for the binary stack size. According to pecoff_v8, there are two fields that control the stack size, SizeOfStackReserve, SizeOfStackCommit.
