Re: How to recover from a EXCEPTION_STACK_OVERFLOW?

Hallo Aurelien!

Hello,

- modifying ESP by hand (risky)


static LONG __stdcall CrashHandlerExceptionFilter(EXCEPTION_POINTERS* pExPtrs)
{
if (pExPtrs->ExceptionRecord->ExceptionCode == EXCEPTION_STACK_OVERFLOW)
{
static char MyStack[1024*128]; // be sure that we have enought space...
// it assumes that DS and SS are the same!!! (this is the case for Win32)
// change the stack only if the selectors are the same (this is the case for Win32)
//__asm push offset MyStack[1024*128];
//__asm pop esp;
__asm mov eax,offset MyStack[1024*128];
__asm mov esp,eax;
}

// TODO: ...
}

Thanks. I guess I can no longer use pExPtrs after modifying esp, nor any local variable even if declared after the change?
