Try using scm_internal_stack_catch instead.

It will store information about the error which you can retrieve with

  scm_fluid_ref (SCM_CDR (scm_the_last_stack_fluid))

You can, for example, pass this information to:

SCM_DEFINE (scm_display_error, "display-error", 6, 0, 0,
           (SCM stack, SCM port, SCM subr, SCM message, SCM args, SCM rest),

(you get the last four args as argument to your error handler)

scm_display_error will display filename and position information.
