debugging

[Brian S McQueen]

I have been using guile to handle the logic of a project (also to make the
project fun).  Anyway, I needed to do a bit of debugging yesterday, and I
decided to finally try to figure out the guile debugging tools.  I think I
found the right stuff, but I am puzzled by the results.  Near the top of
my guile script I put:

(debug-enable 'backtrace)
(debug-enable 'debug)
(debug-enable 'trace)

This seemed to do nothing.  What am I missing?

I was hoping for a stack dump or syntax error reporting.  For some reason
I get no diagnostic information at all from my embedded scheme
interpreter, but the command line guile has plenty of diagnostic
information.  How do I get this diagnostic information into my embedded
interpreter?

I've got the same problem.  Worse, actually, as things blow up for me 
then and there.  I tried to cut-n-paste the appropriate ice-9 code 
into my app, but wasn't able to conclude much, other than that
there seems to be a bad interaction between debugging and modules...
