Bug in Guile 1.8.7, ice-9/debugging/ice-9-debugger-extensions,scm

[Ian Hulin]

The finish command in the debugger crashes with the following error:

Internal debugger error:
usr/share/guile/1.8/ice-9/debugger/command-loop.scm:51:6:
In procedure throw in expression (apply throw key ...):
usr/share/guile/1.8/ice-9/debugger/command-loop.scm:51:6:
Unbound variable: trace-trap

If you change Line 41 of
ice-9/debugging/ice-9-debugger-extensions.scm
  from
   (use modules (ice-9 debugging steps)
to
   (use-modules (ice-9 debugging steps)
	     (ice-9 debugging trace))

This fixes the crash and the debug finish command works as expected.

We are using guile in for the Lilypond project and it would be helpful 
if this could be fixed in the guile sources.

Also has this been fixed in Guile V1.9?

Thanks in advance for your help,

Cheers,

Ian Hulin

Thanks, applied. (8 months late, but better late than never, right?)

In 1.9 the debugging interfaces are being rewritten, and this code will
probably be replaced with something else.

Thanks,

Andy
