Forum: Ruby Has anyone experience using Xcode to debug a Ruby C extension?

I have a C extension, I use Rakefile with extconf.rb, mkmf, rspec, etc.

I have SEGV's in my C extension and I need to debug the C code.

I am on a Mac.

Does anyone have any instructions on how to spin up Xcode with a rspec
test, and be able set breakpoints in C code?

GDB instructions would be tolerable if that's all we have at our
fingertips.

Brute force with printf is not working for me.
