How can I cause embedded guile interpreter to not call abort() on syntax errors?

How can I cause embedded guile interpreter to not call abort() on syntax errors?

[he11hawk]

Hi All.

I'm using guile for scripting inside a long-running task (number crunching).
Unfortunately, if there's an error in the script, libguile calls abort(),
and that kills the entire process, aborting all calculations.  I'd like
instead to get it to behave like the standalone guile does - just display a
message and continue.  I tried to understand how top-repl works in
boot-9.scm, but failed miserably.  Is there an easy way to get this done, or
will I have to adapt top-repl to my needs somehow?

Currently, I simply call scm_c_eval_string with my script.
Thanks.

Have you looked at scm_internal_catch? Some explanations can be found
in guile source, throw.c. I used it successfully in my libtour project
(see http://freshmeat.net/projects/libtour, scmfunc.cc) for both call
and eval.
