Hi Joel,

Please no Fortran exceptions.  GDB is buggy even for plain C, see:
	Copy-Relocate debug error
	http://sourceware.org/ml/gdb/2012-01/msg00120.html

I can look at it myself but only later this week.

Some such order may be what ld.so does for the symbol search which should be
the real right solution.

Except for that there is probably wrong debug info in some cases from GCC and
(a) I believe GDB should try to be compatible with current widespread buggy
GCC debug info, (b) We may try to propose fixing the GCC produced debug info
but I have no idea how yet, some such possibilities were described in
	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40040


Thanks,
Jan
