Hi,

I am debugging a 64-bit Intel app in Xcode/gdb. Memory is being stomped, so
I am trying to set a watchpoint. It appears the watchpoint is set
successfully, but it is never hit, even though the data does change in the
memory location being watched.

In a 32-bit test app, a watchpoint works properly, but in a 64-bit version
of the same test app, the watchpoint has no effect.

Is this a known problem? Are watchpoints simply broken for 64-bit Intel
apps? Is there something I'm missing?
