[uml-devel] debugging UML cores

[Joe M. <gm...@no...>]

Hi UML developers,

I am getting a variety of cores from UML - fairly intermittent. The bad 
part is that examining these cores with GDB is utterly fruitless (for 
me). Are there some tricks beyond the normal stuff below I should be 
doing to get a better sense of what is going wrong? I see no back trace 
and no thread info. thanks for any help, Giovanni
