Error in `gdb.prompt_hook` might cause infinite loop #21

If we set gdb.prompt_hook as following:

x = 0

def foo(current_prompt):
    global x
    if x & 1:
        x += 1
        raise gdb.error("err")
    x += 1
    return "(test) "

gdb.prompt_hook = foo

GEP will step into an infinite loop after the first prompt.
