How do I increase the stack size in python

Question

I have a python program that uses a custom-built DLL. This DLL crashes due to a stack overflow. This overflow is not due to a recursive function gone bad, but to large allocations on the stack using alloca().

I want to increase stack size to get rid of this error. Is there any way to do this?

Answer 1

The functions in a dll can have no control over the stack size available when they are executed (unless you spawn new threads under the control of your library).

If the dll is custom, then can't you allocate on the heap rather than stack (or statically allocate, if appropriate), and stop the problem that way?
