* module/ice-9/boot-9.scm (catch): Signal an early error if the handler or pre-unwind handler types aren't right. This is more important than it was, given that we dispatch on type now when finding matching catch clauses. * libguile/vm.c (vm_expand_stack): Use the standard scm_report_stack_overflow to signal stack overflow. This will avoid running pre-unwind handlers. * libguile/throw.h: Move scm_report_stack_overflow here. * libguile/throw.c (catch): Define a version of catch in C. (throw_without_pre_unwind): New helper. Besides serving as the pre-boot "throw" binding, it allows stack overflow to throw without running pre-unwind handlers. (scm_catch, scm_catch_with_pre_unwind_handler) (scm_with_throw_handler): Use the new catch in C. (scm_report_stack_overflow): Moved from stackchk.c; throws an unwind-only exception. * libguile/stackchk.h: * libguile/stackchk.c: Remove the scm_report_stack_overflow bits.
