(fhpd) break main
gets infinite reports of the breakpoint main being hit.
this is caused by the breakpoint code not injecting a "breakpoint-hit" event
into the stepping engine.
This function, even without optimization, degenerates to one instruction after
the function prologue: a jump to itself. The address of the breakpoint is this
instruction. For reference, gdb shows the same behavior with optimized and
optimized version of the function.
