>Description:
Save the following code as "foo.cpp":
/* snip */
struct Menu {
class ButtonGadget {
public:
virtual bool HitTest(void);
};
};
bool Menu::ButtonGadget::HitTest(void)
{
return false;
}
int main(int argc,char **argv)
{
return 0;
}
/* snip */
With the instructions given below, gdb (GNU gdb 5.2.1) will not be able
to find the method "Menu::ButtonGadget::HitTest". This might also be a
gdb problem.
>How-To-Repeat:
Save the above code, then compile it with
$ g++-3.2 -O0 -ggdb foo.cpp
The result will be an "a.out" file. Run gdb as follows:
$ gdb a.out
Then try to set a breakpoint at "Menu::ButtonGadget::HitTest".
This command will result in:
GNU gdb 5.2.1

Bug#177433: gcc-3.2 on m68k: internal compiler error while compiling texmacs
Package: gcc Version: 3.2.2 Gcc-3.2.2 produces an internal compiler error on compiling the texmacs package, version 1.0.1-2. Window/Widget/Scrollable/scrollbar_widget.cc: In member function `virtual void scrollbar_rep::handle_set_coord1(event_ptr)': Window/Widget/Scrollable/scrollbar_widget.cc:51: Internal compiler error in instantiate_virtual_regs_1, at function.c:3980 Please submit a full bug report, with preprocessed source if appropriate. This package builds on all other architectures supported by debian. Furthermore, texmacs 1.0.1-1 compiled fine on m68k using gcc-2.95-4. A complete build log can be found at http://buildd.debian.org/fetch.php?&pkg=texmacs&ver=1.0.1-2&arch=m68k&stamp=1042589760&file=log&as=raw -Ralf. --
