Subject: Re: Leaving visible breakpoints in memory/core (Was: 	Breakpoint	stepping)

Message-ID: <20070712024947.9F7354D0489@magilla.localdomain> (raw)
In-Reply-To: Mark Wielaard's message of  Wednesday, 11 July 2007 11:47:12 +0200 <1184147237.4322.18.camel@dijkstra.wildebeest.org>

This is something that you get for free from the "fancy VM tricks"
facilities that are still pie in the sky, but is more or less hopeless
short of that.  So I just wouldn't worry about it any time soon.  The best
I think we can do for now is just remove the breakpoints when you know it's
about to dump core.  This is pretty easy (at least in utrace-based
interfaces) since you just catch the "signal that is about to try to dump
core" event, which you were probably catching already, and it clearly
distinguishes "definitely about to die" from "might run a signal handler
and survive".


Thanks,
Roland
