I'm afraid I only have two general ideas.
1. You can use gdb_print and gdb_output to see the Scheme values of SCM
variables. For example, to see the value of `l', in the top frame of
your backtrace:
(gdb) call gdb_print(l)
(gdb) p gdb_output
2. You can try modifying your script in small ways to see if the problem
disappears. If it does, that may give a clue about what the problem is.
Regards,
Neil
