Is there a reason you decided to go ahead with passing 'data->error'
directly to the parsing functions instead of adding some global state
for recording errors, like a globally accessible 'parse_events_error'?

Because I notice that if someone wanted to improve the breakpoint
parsing code, they'd basically need to make the same changes you've
made in this patch.
