eval doesn't seem to work

[ghost]

If the following code is the correct way to call eval, it doesn't work (Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64 bit (AMD64)] on win32). Not really use this, but maybe some Python modules do.

import nimpy

let py = pyBuiltinsModule()
echo py.eval("3+3").to(int)

nimpy.nim(1185)          callMethod
nimpy.nim(1182)          callMethodAux
nimpy.nim(1165)          raisePythonError
Error: unhandled exception: <class 'SystemError'>: frame does not exist [Exception]

I assume only direct calls to eval dont work, because the following does work:

file eval.py:

def eval_result(code):
  return eval(code)

import nimpy

#let py = pyBuiltinsModule()
let pyEval = pyImport("eval")
#echo py.eval("3+3").to(int)
echo pyEval.eval_result("3+3").to(int)
