Here is a suggested patch. SEH will now not catch BREAKPOINT exceptions.

With a release build of python, I have a similar behavior on both 2.5 and 2.7;
the messages are different though:
2.5: WindowsError: [Error -2147483645] One or more arguments are invalid.
2.7: WindowsError: exception: breakpoint
Kristján Valur Jónsson krist...@ccpgames.com added the comment:
I _think_ that in our old 2.5 python (which had a backported ctypes from 2.6 to
support 64 bits) we always got the JIT debugger i.e. with _ctypes.pyd and
_ctypes_d.pyd.
This api, DebugBreak always invokes the JIT debugger,
ctypes has _always_ catched exceptions raised in function calls.
On Windows ;-).

New submission from Kristján Valur Jónsson krist...@ccpgames.com:
import ctypes
ctypes.windll.kernel32.DebugBreak()
This used to be a handy way to attach a debugger to a running program, by way
of JIT debugging. Now ctypes catches and handles this exception so a debugger
is never invoked.
