Frame issue with the debugger plugin
oBFusCATed:
2. Yes, it should be more portable. Otherwise why they'll add a macro. Probably it is not implemented by vc++, but we don't care much about it anyway.
3. This will require more changes. Probably track where the original value for the frame index is taken from and see why it is a long instead of uint32.

Well, I think that is what needs to be done. I think I spoke too soon that it worked, it's broken again for no obvious reason. Another issue, looking at the wxstring documentation, it has an 'operator<<' defined for a 'wxlonglong_t' type. From my understanding of 'wxlonglong_t' definition, it is defined as 'long long' for 64-bit compilers matching the definition of 'size_t'. That means 'operator<<' with an argument of 'size_t' should work correctly on a wxstring object. Can you please point me to the piece of code where the frame info is parsed, is it 'GDB_driver::ParseOutput'?
oBFusCATed:
Have you tried using a debugger to trace where bad value is generated from?
It is perfectly possible to debug cb, while debugging another application. It is a little odd, but works:)
scarphin:
Yes, many times but I quit after getting errors like:
--- Code: ---Backtrace stopped: previous frame inner to this frame (corrupt stack?)
--- End code ---
I don't know if it's CB related or something else but I can't deal with it. If you want to see the debug log:
--- Code: ---Active debugger config: GDB/CDB debugger:GDB
