When I try to disable or delete an Hardware watchpoint on my program (that use some windows dlls without debugging symbols (gtk, kernel32, ntdll...) ans is multithreaded (32 threads)), the program still stop on it and send a SIGTRAP.
When I use the info break command, the watchpoint is disabled or is deleted in the list.

On a multithreaded program :
watch a variable : watch &a
continue : c
when break on a change : disable Num(watchpoint number)
continue : c
