hi,


I have a nasty coredump; this is with fairly recent CVS (ChangeLog
timestamp 26/12). Any thoughts?  This is from within LilyPond.  The
only funky thing was that the file was doing some operations with a
trivial GOOPS class. Any ideas?

I've seen something like this when an error (an ordinary scheme level
error) occurs in code generated by a procedure->macro.  Dunno if
that's what's happening here.  Running without --debug normally avoids
the segv (though obviously one can't tell quite where it went wrong).

Yeah, I found out so far. Now I have to figure out what in my 10000
lines of Scheme code is causing

	ERROR: In procedure car:
	ERROR: Wrong type argument in position 1: ()

Does anyone actually know how the evaluator works?

The error you describe could certainly be caused by the statement (car 
'()), but this is not what you are referring to?

Surely a backtrace would help you pinpoint the problem?  Is there a
reason why you can't get a backtrace for this error?

Maybe I should mention that this is both for 1.6.* and for 1.7
and of course for (array? ..) as well.

It would of course be consistent if
(if (array? '(a b c))
    (array-ref '(a b c) 0))
would return 'a without errors, but this is not really
what we want I guess...

Yeahh, and 

    (uniform-vector? 'foo)
    => #t

    (uniform-vector? (expt 2 60))
    => #t

    (uniform-vector? 1.0)
    => #t

    (uniform-vector? 1+i)
    => #t

unif.c is totally botched, I'd say.  We need to redo it completely.
