 Hi

 Mountain Lion OS X 10.8.2, XCode 4.5.1, MacBook Pro 2.4 GHz Intel Core i7,
 4 GB 1333 MHz DDR3

 I have successfully installed MacPorts gcc-mp-4.7. And, gdb 7.5 appears to
 have installed successfully. I can build a simple Hello World  C program
 but when I try to debug it with gdb I get one possibly two separate
 errors.

 Below is a sample build and debug session:

 {{{
 macbook:test john$ make
 gcc-mp-4.7 -Wall -std=c99 -pedantic -g -O0 hello.c -o hello
 macbook:test john$ ls -l
 total 40
 -rw-r--r--  1 john  staff    69 25 Oct 15:20 Makefile
 -rwxr-xr-x  1 john  staff  8756 25 Oct 15:22 hello
 -rw-r--r--  1 john  staff   110 25 Oct 15:22 hello.c
 drwxr-xr-x  3 john  staff   102 25 Oct 15:22 hello.dSYM
 macbook:test john$ ggdb hello

 Any help would be greatly appreciated with the BFD error and guidance on
 how to solve the code signing issue.

 John
