PRecord sets memory even when it says it did not


Hi Hui,

I'm seeing PRecord changing memory even though I answer
the query as to not change it.  Please see below.

Thanks

Marc

Because GDB is in replay mode, writing to memory will make the execution log unusable from this point onward.  Write memory at address 0xbffff6a0?(y or [n]) n
Process record canceled the operation.
(gdb) p a
