[Sbcl-help] sbcl & gdb

[Peter K. <ps...@cs...>]

Hello,

I'm working on some code which goes between a few different runtimes
of various languages, C, C++, Lisp, C#, etc.

What are some tricks I can do to get gdb and SBCL to play together nicely?
I often get the "continuing with fingers crossed" and whatnot even before
I get up to a prompt in SBCL. 

What signals should I ignore, is there a nice way to get a backtrace through
the lisp function calls as I unwind through them when starting from a C
stack frame, etc, etc, etc.

An example of something like this when debugging with C#'s runtime and
gdb is (in .gdbinit):

########################################
handle SIGXCPU SIG33 SIG35 SIGPWR nostop noprint

define mono_bt
 select-frame 0
 set $i = 0
 while ($i < $arg0)
   set $foo = (char*) mono_pmip ($pc)
   if ($foo)
     printf "#%d %p in %s\n", $i, $pc, $foo
   else
     frame
   end
   up-silently
   set $i = $i + 1
 end
end
########################################

Is there a similar thing for sbcl to poke around a map of text segment
addresses to internal SBCL calls?

Thank you.
