[Openmcl-devel] unhandled exception in (i think) printer circularity testing

Sun Aug 7 02:00:05 PDT 2005

i'm running into this problem using ucw's backtrace inspector. using
slime's backtrace function (which is does some low stack walking) i'm
attempting to print (to a character stream tied to a socket) the
locals on the stack. the error is always in numberp, the frames on the
stack are always more or less the same and the address is always
#f1f. playing with *print-circle* and *print-pretty* doesn't seem to
change things.

it could very well be that the locals i've colllected from the
backtrace were dynamic-extent and so don't exist anymore (this is my
uneducated guess), if so is there a way to test for this condition?
