Make sure to unlink the related breakpoint when the watchpoint instance is deleted. This prevents having a wp-related breakpoint that is linked to a NULL watchpoint (e.g. the watchpoint instance is being deleted when the 'watch' command fails). With the below scenario, having such a left out breakpoint will lead to a GDB hang, and this is due to an infinite loop when deleting all inferior breakpoints. Scenario: (gdb) set can-use-hw-watchpoints 0 (gdb) awatch <SCOPE VAR> Can't set read/access watchpoint when hardware watchpoints are disabled. (gdb) rwatch <SCOPE VAR> Can't set read/access watchpoint when hardware watchpoints are disabled. (gdb) <continue the program until the end> >> HANG << Signed-off-by: Mohamed Bouhaouel <mohamed.bouhaouel@intel.com> Reviewed-by: Bruno Larsen <blarsen@redhat.com>
