With a pattern matching library I am generating some Python code that matches patterns. For a very big pattern set I generate a Python file which is about 20MB and has ~300K LOC. When I try to execute the file with Python 3.6.2 on Windows 10 (64bit), the interpreter crashes. I do not have the Python source locally, but I could get it if necessary. The crash is because of a stack overflow when calling dfs() in compile.c. I can attach you the program, but it needs some dependencies which currently are only availiable via some Github repos.

I will try to split the ig file into multiple smaller ones, but I thought you might want to know about an interpreter crash.
