Description of Problem:
When using ddd, having a breakpoint set in a function, often the source file
will fail to load completely resulting in an inability to watch the step-through.
It seems to be reproducible per breakpoint/source file, as other breakpoints in
the same session and run of the application being debugged work as expected
(mostly - the 'current line' pointer also seems to be somewhat confused).
it seems to be fixed in 3.3.7-3, which is available in rawhide soon.
