Here are some more tests:
1. It doesn't get stuck when debugging a "hello-world.c" program. Thus it
depends on the executable.
2. Regarding toggle-debug-on-quit and C-g, it doesn't work. No backtrace is
produced and the CPU continues to be at 100%.
3. I tried running edebug on gdb, which wasn't easy. I had to manually
first do eval-buffer on gdb-mi.el and gud.el. But in the end I managed and
found that the CPU is spend during (run-hooks 'gdb-mode-hook) . I'll try to
investigate it further in the next few days.
Regards,
Dov
