[issue20434] Process crashes if not enough memory to import module

[Eric Snow]

Eric Snow added the comment:

I was going to say we should consider changing the API of _PyBytes_Resize() and _PyString_Resize().  However, having looked at the two functions, I guess it makes sense.

Looking at the patch, I'd argue that we still need to set the string to NULL in the error case.  Only in the out-of-memory case do the two functions change it to NULL for you.
