hmm it seems im getting closer to iron out where the bug appears. 

     3880    #if defined(TARGET_SYSTEM_ROOT_RELOCATABLE) && !defined(VMS)
     3881      /* If the normal TARGET_SYSTEM_ROOT is inside of $exec_prefix,
     3882         then consider it to relocate with the rest of the GCC
installation
     3883         if GCC_EXEC_PREFIX is set.
     3884         ``make_relative_prefix'' is not compiled for VMS, so don't
call it.  */
-    3885      if (target_system_root && !target_system_root_changed &&
gcc_exec_prefix)
     3886        {
-    3887          char *tmp_prefix = get_relative_prefix
(decoded_options[0].arg, // decoded_options throws the BADF00D according to gdb
     3888                              standard_bindir_prefix,
     3889                              target_system_root);
-    3890          if (tmp_prefix && access_check (tmp_prefix, F_OK) == 0)
     3891        {
-    3892          target_system_root = tmp_prefix;
-    3893          target_system_root_changed = 1;
     3894        }
     3895        }
     3896    #endif

if i do a memory dump on the call to decoded_options in insight the first 10
registers show {0xbaadf00d} funny name btw. 

maybe a bad pointer somewhere ?
