The problem where Fortran causes gdb to say

gdb: Internal error: Unexpected debugging symbol type 't' at symnum -2147269732.

is due to Fortran's using N_GSYM for typedefs.  Here's a fix, in dbxread.c
function read_dbx_symtab, at around line 2307:
 
	    case 'G':
	      ADD_PSYMBOL_TO_LIST (namestring, p - namestring,
				   VAR_NAMESPACE, LOC_EXTERNAL,
				   global_psymbols, bufp->n_value);
	      continue;

+	    case 't':
+	      continue;

	      /* I don't think the default case should happen.  A breakpoint
		 here to check would probably be good.  */
