scan_code can call all.extend when all is None

[anonymous]

The scan_code function in mf.py has a bug that allows this line to be executed when all is None:

all.extend(all_nested)

This is line 960 in v.1.5.1.

The bug is still present in the trunc as of the date this ticket was created (2011/08/26).

When hit this bombs out the PyInstaller? run so I am giving it a high priority.

How can be this bug reproduced? Any code example?

[OP here] It happened with one of our (large) projects but not another: don't know what in specific is triggering it. But it is pretty clear that there is a code path where all is None when it gets to the line that calls all.extend. My patch is simply this line before the all.extend line:

if all is None: all = [] #Ticket405 Patch
