           Summary: Infinite loop in user32_winetest
           Product: ReactOS
           Version: unspecified
          Platform: VMWare 3
        OS/Version: ReactOS
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: Win32
        AssignedTo: ros-bugs at reactos.org

back teace

When I run user32_winetest msg (and disable all the previous tests that
hang/crash reactos) , it falls in an infinite loop and the result is that the
stack grows so much that it stops in the following assertion in the kernel:
Assertion '((PCHAR)Thread->Tcb.StackBase - (PCHAR)Thread->Tcb.StackLimit) <=
(KERNEL_LARGE_STACK_SIZE + PAGE_SIZE)' failed at ntoskrnl\mm\procsup.c line 263

The test actually tests if the window proc of a window can create an infinite
loop by adding a messge loop insiede the window proc. However the measure of
the test to decide if it is indeed in an infinite loop is 256 recursive calls,
but it needs just 50 recursiv  calls to make the stack too big to crash the
kernel.

The backtrace and the location of the infinite loop is in the attached file
