What can I do to get a stack trace?
I'll let people more knowledgeable than I am on OS X anser. But at
a minimum, compile the bindings with debug info (-g). And then
maybe use this:
Would I do that with an invocation like this somehow:
sudo gem install libxml-ruby -- --with-compile-flags=-g
I also have the libxml-ruby gem code checked out -- should I modify
the rake task that builds the extensions:
ext = Config::CONFIG["DLEXT"]
task :extensions => ["ext/libxml/libxml_ruby.#{ext}"]
file "ext/libxml/libxml_ruby.#{ext}" =>
["ext/libxml/Makefile"] + FileList["ext/libxml/*.{c,h}"].to_a do |t|
Dir.chdir("ext/libxml") { sh "make" }
end

That's interesting -- I'm going to see how it works.
The other way is to use gdb to load ruby, and then run the script.
I've seen instructions elsewhere for doing that.
