[cfe-dev] UNREACHABLE executed when conpiling Python code

[Shang Yu]

Got it! There is a header file which has following declaration:
extern __declspec(dllimport) int (*PyOS_InputHook)(void);
and in myreadline.c there is a line:
int (*PyOS_InputHook)(void) = NULL;
these 2 lines will trigger assert failing. Is there some switch to
avoid this ? In MSVC this is just a C4273 warning. Many thanks!
