debugging on linux: strange symbols, files open twice, "nothing to be done"

Right, this seems to be some kind of gcc/gdb bug.
This bug can be circumvented by removing the "virtual" keyword from the TestDebugger class' ancestors list


--- Code: ---class TestDebugger : public foo::Base1 ,public Base2
--- End code ---

That would work in my reduced test-case... but the real classes are derived from a class doing the reference-counting so that would introduce diamond inheritance problems :-(

Edit: I'll report it to the gdb people.

Jenna:
Have you tried to use a pointer ?


--- Code: ---TestDebugger* iAmTheBug;
--- End code ---

That works for me in the test-case.

Thanks, nice workaround :-) That way I can actually debug it.

(emphasis added)

Which is why you shouldn't create such objects on the stack but only on the heap...
So, Jens is right (again) :) :
