no attribute '_handle_missing_debuginfo'

[Robert Dubner <rdubner@symas.com>]

I admit defeat, and I throw myself on the mercy of the court.

I really tried.  I searched the internet.  I spent some time digging
through the GDB source code.  But I have been thwarted by the sheer number
of moving parts.

One line background as to why I am compiling GDB:  I am part of an effort
to build a COBOL front end for GCC, and I am making modifications to GDB
to handle the idiosyncracies of COBOL executables.

That said: When I compile and run GDB, I am getting the following
announcement on stderr:

===
Python Exception <class 'AttributeError'>: module 'gdb' has no attribute
'_handle_missing_debuginfo'
===

I believe in my heart that this has to have a simple cause, and I believe
that somewhere there is a switch that can be moved from "broken" to
"fixed" and the message will go away.

But I haven't been able to find it.

I hope some kind soul can embarrass me with a fix.  Go ahead.  I can take
it.

Thanks!

I just now built and compiled the GDB master branch 3f30f11f6d5, which was
committed on 2024-10-07
