It is the case - thanks!
Is it "nothing can be done about it" case?
Is there an already submitted bug?
Not sure if there is a bug report. I am not even sure if this is:
- an issue in gdb
- an issue with the debug info generated by fpc
From very far memory.... fpc generates some kind of "jump table"
(actually it may be a bit more than a jump table) for each class that
implements an interface.
Calling a method of an interface first calls the code in that table, and
then goes to the actual method.
gdb somehow thinks that the code in the table can not be stepped, and
skips the entire call.
Maybe fpc could add debug info, not sure what is available in each of
the stabs/dwarf2/3 standards that could be used to tell gdb.
Btw, have you tried dwarf 3? I never tested, so maybe.... / But be
aware, dwarf3 has other instabilities (gdb crashes)
