GSYM does not contain:
- variable information (locals, parameters, globals, statics)
- type information
- macro information
- unwind information (but will soon be available)
- line entries don't contain anything but function + file + line (no source 
column, is statement, end sequence, end prologue, begin elilogue, etc).
