# The breakpoint is probably at the instruction where the value being

# watched (myrec.x) gets updated.  This is the instruction where we

# expect to receive a watchpoint notification when we do the "stepi"

# below.  However, having the breakpoint at the same location as this

# intruction can possibly interfere with our testcase, as stepping

# over the breakpoint in order to get past it may incorrectly lead

# to the debugger missing the watchpoint hit.  This would be a bug

# in GDB, but this is not the bug that we are trying to test here.

# So, we remove all breakpoints first.
