Hi all,
I've just committed a fix (r19253) which makes it possible to call
virtual methods within GDB. (Or other Dwarf-debuggers, when they
support that properly)
Only problem is that when GDB is in Pascal mode, it won't work. I have
written a patch for that
(http://cygwin.com/ml/gdb/2011-09/msg00072.html) or you can set GDB to
use C, and then call the virtual function.
Ah, cygwin => I have never tested the gdb from them. I always use the
mingw version
Note however that there still could be issues regarding the
calling-convention. With a simple function returning an integer it
works, however. ;)
In theory, it should be possible to prepare the stack, and set the pc
via register modification? But, no, no, no, i do not think it is a good
idea, and probably will bring more new problems.
But there is another issue to be looked into. I haven't done that yet.
- Breakpoints => if in the executed function, any breakpoints are hit...
- Exceptions => I know gdb has some features to restore the stackframe
=> but I have no idea, if that relies on c-style stuff, or would work
with fpc exceptions too.
