no attribute '_handle_missing_debuginfo'

[Robert Dubner]

Baris, thank you for responding.

Your speculation is correct; GDB is my alias to the
"<build_folder>/gdb/gdb" executable in my build tree.  I am in the
position of using the system-installed 'gdb' to debug my locally-built
gdb, so for now I don't want to install the locally-built version.

Your suggestion was accurate.  My locally-built GDB was using the
/usr/share/gdb data directory of the system-installed gdb-12.1

When I specify --data-directory as you described, the " no attribute
'_handle_missing_debuginfo'" message no longer appears.

Fun fact: When --data-directory=misspelled-directory-path is used, a
number of new and exciting error messages appear!

Thank you so much for taking the time to answer my question.
