[issue45563] inspect.getframeinfo() doesn't handle frames without lineno

[Marc-Andre Lemburg]

I see this in modules frozen by the Tools/freeze/ tool.

The line numbers shown for such frozen modules in the frameinfo stack are a bit off as well, compared normal Python. Could this be an indication that there's something not working quite right, which then leads to _PyCode_CheckLineNumber() returning -1 ?

The Tools/freeze/ doesn't do anything special, BTW. All it does is load the module and then store the marshal'ed code objects in C arrays. The information read from those C arrays should be the same as what Python reads from PYC files.
