An Error in Early Boot

[Noah Lavine <noah.b.lavine@gmail.com>]

Hello,

I got into a situation just now when Guile was generating an error
very early in the boot process (it was loading some objcode from
scm_init_eval_in_scheme(), I think, although I haven't looked enough
to be sure). The fun part is, instead of printing an error message, it
got into an infinite recursion that eventually ended in a memory
fault.

The reason is that scm_error_scm in error.c calls scm_ithrow (error.c:315),
which finds its way through scm_throw and some VM calls to
pre_init_throw (throw.c:495)
which in turn gets it to scm_at_abort, which goes to scm_c_abort,
which finally calls scm_misc_error (control.c:210) because it can't
find a prompt on the dynamic stack because the error is too early,
which leads back to scm_error_scm again.

However, I'm not quite sure how to fix this.
