This is also above my paygrade so was waiting for Simon or Prof.
Ripley to chime in, but until then, I do have one suggestion:

I think you need to compile with the -g flag, and you'll probably want
to turn off optimization (I think R CMD BUILD/INSTALL defaults to -O2)
I think you can probably change these "inline" when you do R CMD
INSTALL ... , but I just tweak my Makevars whenever I want to compile
with different settings. I do this be creating the file "~/.R/
Makevars". Compiling with debug flags and no optimization, that file
would look like this:
CC=/usr/bin/gcc -arch x86_64 -std=gnu99
CPP=/usr/bin/gcc -arch x86_64 -std=gnu99 -E
CXX=/usr/bin/g++ -arch x86_64
CXXCPP=/usr/bin/g++ -arch x86_64 -E
OBJC=/usr/bin/gcc -arch x86_64 -std=gnu99
When I want R to use its default settings, I just comment out the
lines in that file.
Maybe when you compile with these args, it might get you closer to
getting your debugger working as you take the rest of the steps that
By the looks of it, you're way more of a C/gdb jedi than I, but
perhaps this might help.
