[slime-devel] Bug in slime with LW

[Alain.Picard at memetrics.com]

Weird problem with the debugger at the moment, with LW.
When do this:


XOS> (setf *break-on-signals* t)
T

I quickly get into this weirdness when a condition is raised
by other (than the REPL) threads:

================================================================
The variable &REST is unbound.
Break entered because of *break-on-signals*.
   1 (continue) Return from break.
   2 Try evaluating &REST again.
   3 Specify a value to use this time instead of evaluating &REST.
   4 Specify a value to set &REST to.
   5 Return from break.
   6 Try evaluating &REST again.
   7 Specify a value to use this time instead of evaluating &REST.
   8 Specify a value to set &REST to.
   9 Return from break.
  10 Try evaluating &REST again.
  11 Specify a value to use this time instead of evaluating &REST.
  12 Specify a value to set &REST to.
  13 Return from break.
  14 Try evaluating &REST again.
  15 Specify a value to use this time instead of evaluating &REST.
  16 Specify a value to set &REST to.
  17 Return from break.
  18 Try evaluating &REST again.
  19 Specify a value to use this time instead of evaluating &REST.
  20 Specify a value to set &REST to.
  21 Return from break.
  22 Try evaluating &REST again.
  23 Specify a value to use this time instead of evaluating &REST.
  24 Specify a value to set &REST to.
  25 Return from break.
  26 Try evaluating &REST again.
  27 Specify a value to use this time instead of evaluating &REST.
  28 Specify a value to set &REST to.
  29 Return from break.
  30 Try evaluating &REST again.
  31 Specify a value to use this time instead of evaluating &REST.
  32 Specify a value to set &REST to.
  33 Return from break.
  34 Abandon this request and wait for the next one
  35 (abort) Quit process.

Type :b for backtrace, :c <option number> to proceed,  or :? for other options

Any clues?  This is a CVS from Thu Jul  1  2004.

Cheers.
