 gdb-rhbz1560010-fix-assertion-symbol-language-dict-language-4of5.patch

;; Fix 'Assertion `SYMBOL_LANGUAGE (sym) == DICT_LANGUAGE (dict)->la_language' failed.'
;; Keith Seitz, RHBZ#1560010.

gdb/23712: Remove dw2_add_symbol_to_list

Finally, we can remove dw2_add_symbol_to_list since the wrapper function
originally introduced to catch this multi-language scenario is no longer
needed.  With multi-language dictionaries, we can now support adding
symbols of multiple languages, negating the need for the assertion
entirely.

This patch should now fix gdb/23712 (and symtab/23010).  At least it will
if the NULL buildsym_compunit problem doesn't strike first (see gdb/23773).

gdb/ChangeLog:

PR gdb/23712
	PR symtab/23010
	* dwarf2read.c (dw2_add_symbol_to_list): Remove.
	(fixup_go_packaging, new_symbol): Use add_symbol_to_list.
