Hm, thanks Andy. I settled on the following solution, no problems:
SCM_DEFINE (libguile_fst_writer_emit_value, "libguile-fst-writer-emit-value",
3,0,0,
(SCM scm_ctx, SCM scm_fsthandle, SCM scm_val),
"Write a change on fstHandle")
{
// Storage for temporary string
char* s = NULL;
scm_dynwind_begin (0);
s = scm_to_locale_string (scm_val);
fstWriterEmitValueChange(SCM_TO_CTX (scm_ctx),
SCM_TO_FSTHANDLE (scm_fsthandle),
s);
scm_dynwind_free (s);
scm_dynwind_end();
return SCM_UNSPECIFIED;
}
Thanks,
Brad

You can write this as scm_dynwind_free (s), FWIW.
Otherwise I didn't see the problem. `s' is not managed by the GC, so
the GC shouldn't have much to do with it.
