Process finished with exit code -1073741571

I'm trying to process a large graph using a recursive algorithm. Due to the deep recursion, I encountered the problem described at Python: Maximum recursion depth exceeded.

So, I tried increasing the limit on recursion depth, like so:

import sys
sys.setrecursionlimit(5000)

However, whatever value I use for the depth, I cannot get the result I want. Either I still get the exception, or else the program just halts with no output on the screen but: Process finished with exit code -1073741571.

How can I solve the problem?

That is the signed integer representation of Microsoft's "stack overflow/stack exhaustion" error code 0xC00000FD.

You might try increasing your executable's stack size as described in the answer here: How to overcome Stack Size issue with Visual Studio (running C codes with big array)

Anytime you see strange, large negative exit codes in windows, convert them to hex and then look them up in the ntstatus error codes http://msdn.microsoft.com/en-us/library/cc704588.aspx

You may also use the MS Error Lookup Tool to find such codes locally, or even automatically. Other, similar tools exist both by Microsoft and third parties.

You could use something like:

if __name__ == '__main__':
    sys.setrecursionlimit(100000)
    threading.stack_size(200000000)
    thread = threading.Thread(target=your_code)
    thread.start()

This solved both my recursion limitation and my heap size limitation.
