New submission from anthony shaw <anthony.p.s...@gmail.com>:
If for whatever reason, Py_Initialize() has not been run or failed to run, any call to Py_CompileStringFlags will call PyUnicode_DecodeFSDefault and the reference to interp will be NULL. There is currently no null reference check in PyUnicode_DecodeFSDefaultAndSize which causes a segfault. https://github.com/python/cpython/blob/master/Objects/unicodeobject.c#L3736-L3737 is the offending line. It might be better to catch the null pointer and raise an unrecoverable error there?
