__Stack usage__
The msvc compiler is quite stack-hungry which might result in a "maximum recursion depth exceeded"
RuntimeError for code with lots of nested function calls.
There are several ways to deal with this:
- increase the threshold used for detection by altering the argument to `mp_stack_set_limit` in `unix/main.c`
- disable detection all together by setting `MICROPY_STACK_CHECK` to "0" in `windows/mpconfigport.h`
- disable the /GL compiler flag by setting `WholeProgramOptimization` to "false"
See [issue 2927]( for more information.
