It looks like bug in xml/sgml backend because without -t option works 
fine.

it's not only specific DSSSL, but also DTD specific. When I took only 
elements that are in my document + entities and replaced PUBLIC identifier 
with dummy DTD (all elements have mixed content any in any) and run jade 
then everything was fine.

The specific DSSSL code is:

(define wrap-math-char (lambda (c)
    (case (math-type c)
    ((#\O) (make element gi: "mo" (literal opr-debug (string c))))
    ((#\N) (make element gi: "mn" (literal num-debug (string c))))
    ((#\I) (make element gi: "mi" (literal sym-debug (string c))))
    (else  (make element gi: "mi" (literal (string c))))
    )
))

When I comment out the line with #\I everything is fine.

The whole DSSSL is at the end of the post. The purpose of this function is 
to wrap all characters in string with elements depending on what class 
they belong to (this is conversion to MathML).

The code:

(define wrap-math-char (lambda (c)
    (case (math-type c)
    ((#\O) (make element gi: "mo" (literal opr-debug (string c))))
    ((#\N) (make element gi: "mn" (literal num-debug (string c))))
;    ((#\I) (make element gi: "mi" (literal sym-debug (string c))))
    (else  (make element gi: "mi" (literal (string c))))
    )
))

does not cause SIGABORT.

Yes, exactly:

Name        : openjade                     Relocations: /usr
Version     : 1.3.1                             Vendor: Red Hat, Inc.
Release     : 4                             Build Date: Thu 21 Feb 2002 
12:59:13 PM GMT+1
Install date: Tue 17 Dec 2002 09:42:31 AM GMT+1      Build Host: 
daffy.perf.redhat.com
Group       : Applications/Text             Source RPM: 
openjade-1.3.1-4.src.rpm
[.....]

I renamed /etc/sgml/catalog (I do not want to use it). I have 

SP_ENCODING=utf-8

And at the end of cataog file I have:

OVERRIDE YES
SGMLDECL  /usr/share/doc/openjade-1.3.1/pubtext/HTML4.dcl
OVERRIDE NO
CATALOG "/usr/share/sgml/openjade-1.3.1/catalog"

I need it to have UTF8 encoding in documents (I map ISO entities and my 
entities to unicode).

On windows everything is fine (???). DTD is quite big (>1000 entities, 
many files).

DSSSL code http://www.fuw.edu.pl/~mpry/DSSSL/mml.dsl
document:
http://www.fuw.edu.pl/~mpry/DSSSL/bug_org.sgm
FOT produced by openjade
http://www.fuw.edu.pl/~mpry/DSSSL/bug_org.fot
dummy DTD (unfortunately with such a DTD everything is OK)
http://www.fuw.edu.pl/~mpry/DSSSL/dummy.dtd

I suspect that there can be something wrong with entities. Program aborts 
just after entity, eg.:

[....]
></mrow
></mfrac
><msubsup
><mo
stretchy="false"
>&int;</mo
><mi
>-1</mi
><mi
>+&#8734;Aborted

There is one important thing I have to add. In SGML documents entities are 
SDATA, but when I make visualisation transformation (like this conversion 
to XML) I put in catalog file entry pointing catalog, where public 
identifiers of all entities files point to files where those entities are 
simple text entities like:

<!ENTITY Abreve "&#258;">
<!ENTITY Amacr "&#256;">
<!ENTITY Aogon "&#260;">
<!ENTITY Cacute "&#262;">
<!ENTITY Ccaron "&#268;">
<!ENTITY Ccirc "&#264;">
<!ENTITY Cdot "&#266;">
[....]


and sometimes markup (interpreted by properly by backend). That's why I 
have -w no-valid option.

And one more question:
Does CR/LF in DTD document and DSSSL files has any meaning? I have them 
mixed (some files prepared in DOS, some in Unix).
