Is there any chance you could try a newer gdb?

This bug seems very strange; but if there was a missing
initialization (seems improbable but you never know),
it seems like it would have been fixed since 8.0.

Also, that function isn't in the current sources and, importantly,
isn't mentioned anywhere in the ChangeLogs. So maybe it is a
Fedora patch? Sergio?

Tromey,

No real chance I can install a later version at this time. I reported the
bug only because the gdb output requested it and I was trying to be a good
citizen. I've since been able to get passed the issue by slimming down the
operant .gdbinit file and loading the path, and file information, etc. at the
gdb prompt. For some reason the issue doesn't occur under those conditions.
It may very well be a fedora patch at the root of things.

Mike
