Good idea ! Now I got a real backtrace:

[norwegen@voyager helloworld]$ gdb 
~/packages/BUILD/jade-1.1_1/jade/jade/jade
GNU gdb 4.17
This GDB was configured as "i386-redhat-linux"...
(gdb) break main
Breakpoint 1 at 0x8049703
(gdb) run -t sgml -d ../../docbook/html/docbook.dsl helloworld.sgml
Starting program: /home/norwegen/packages/BUILD/jade-1.1_1/jade/jade/jade
- -t sgml -d ../../docbook/html/docbook.dsl helloworld.sgml

Breakpoint 1, 0x8049703 in main ()
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

Well, this doesn't tell me much, but it's better than the first one ...

Is there any _working_ version of jade >= 1.1 somewhere ?
