Changeset 14484 for trunk/source/lisp-kernel/lisp-debug.c

Message:

When in batch mode, reset the signal action for SIGSEGV and SIGBUS
to the default before trying to print a backtrace in the lisp kernel
debugger. The idea is to avoid looping on "unhandled exception 11"
or whatever when trying to print out a trashed call stack.

Also print version information before the backtrace, so that we see
it if printing the backtrace fails.
