To my knowledge OS X also supports DWARF debugging symbols, cf.
http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00745.html

However, with DWARF the result is the same.

I might miss something, but the line numbers look OK.

It does and seemingly the debug location used for this is the line of the last
variable declaration.

It is actually not quite clear how gfortran should handle this - simply not
allowing a break point in line 6? Or ... ?
