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.
