I'm nobody but I don't find your argument compelling. I suggest you go
read: http://msdn2.microsoft.com/en-us/library/ksazx244.aspx
In short, you can tell the CRT to do whatever you like when the
parameters are invalid, including returning EINVAL.
void VS2005_CRT_invalidParamHandler(const wchar_t* expression,
const wchar_t* function,
const wchar_t* file,
unsigned int line,
uintptr_t pReserved)
) { errno = EINVAL; }
int main() {
// Disable VS2005's parameter checking aborts
_set_invalid_parameter_handler(VS2005_CRT_invalidParamHandler);
// Disable message box assertions
_CrtSetReportMode(_CRT_ASSERT, 0);
...
}
I went back and read more of the older discussion. And I think your
position is that you just don't want to force another compiler on
people, but aren't developers used to this? And if the Express Edition
(free version) is the target, there is no monetary reason to avoid the
upgrade. And as others have said, a VS2005 version of python is faster.
For reference, http://msdn2.microsoft.com/en-us/library/ms235497.aspx
contains the list of CRT breakages according to MSFT.
