Comment:
Assigned to Guido because there's a policy issue.
This implements Jack's PyOS_CheckStack for the combo of Windows and MSVC.
The question is whether you think there's a general approach waiting to be had here (I don't, except for adopting Stackless), or whether platform-specific tricks are the best we can do.

Comment:
The semantics of the stack are completely implementation dependent so I wouldn't know how to do this platform-independent. This looks fine to me -- but when I test it (VC 6 on Win98), it doesn't work. Try this:
class C:
def __getattr__(self, a): return self.x
C()
This still aborts the program.

Comment:
And are you sure you tested this?
As shown it breaks the build for _sre because the declaration for PyOS_CheckStack() doesn't use DL_IMPORT(). (MSVC 6.0 on Win98.)

Comment:
bumped stack margin to 8k on a 32-bit box (same as on the Macintosh). this solves the __getattr__ problem, as well as bug #110615.
also: fixed the DL_IMPORT problem.
