flatten-codes "invalid D" about ikarus HOT 7 CLOSED

Fixed in 1515.

To help narrow it down, I think this is happening when the library
is instantiated because check-report should just evaluate to a
procedure.

Actually, importing expands the library but may only partially
compile it all the way to machine code. Code generation only
happens when the library is invoked (which is what happens when
you reference one of its exported variables such as in this case).
[this is why there is a small lag when you import a library and
another when you reference its exported variable]

hello,

i've just updated ikarus (to 1519) and am now seeing this bug (as below) for the first time (had not updated in some months).

the test case is the same startup script i've used for some time (ie. used to work) but has quite some dependencies...

(import (rhs) (sosc) (rsc3))
(define with-sc3 with-udp-sc3)

gives:

Ikarus Scheme version 0.0.3
Copyright (c) 2006-2008 Abdulaziz Ghuloum

Unhandled exception:
Condition components:

1. &error
2. &who: flatten-codes
3. &message: "invalid D"
4. &irritants: (#["fvar" 3])

no idea how to start helping with this? (the source archives are at http://slavepianos.org/rd/sw/ or i can send just the three relevant files in an email?)

regards,
rohan

It would help if you could tar/zip the files needed for me to run the
libraries to pinpoint the error. I tried digging into your archives
but couldn't find where the sources are. Thanks.

This doesn't look like the right ikarus. It's supposed to print the
revision number, no?

I just tried building your libraries (from darcs), and got:

Ikarus Scheme version 0.0.3+ (revision 1521, build 2008-06-19)
