[Qemu-devel] Problem with watchpoint in gdbstub

[Jun Koi]

Hi,

I am trying to debug a VM using gdb. I connected gdb to Qemu (latest
code from git repo), and issued below command:

...
(gdb) watch *0x77f44cd8
(gdb) c

The idea is to catch the write access to address 0x77f44cd8.

But after the "c" command, I saw that the window title of my VM
continuously flip between "QEMU [Stopped]" and "QEMU", non-stop.
This makes the VM unusable.

Is it a bug? Anybody sees the same problem?

Thanks,
Jun
