Hi, Joel, I did what you suggest. Finally, I definitely found that this issue was introduced by your patch in:

Ada: allow unqualified function names in linespecs

This is the meat, where we replace the old la_symbol_name_compare
language method with the new ada_get_symbol_name_match_p.
It fixes the problem when trying to insert a breakpoint on "+".


         * language.h (symbol_name_match_p_ftype): New typedef.
         (struct language_defn): Replace field la_symbol_name_compare
         by la_get_symbol_name_match_p.
         * ada-lang.c (ada_get_symbol_name_match_p): New function.
         (ada_language_defn): Use it.
         * linespec.c (struct symbol_matcher_data): New type.
         (iterate_name_matcher): Rewrite.
         (iterate_over_all_matching_symtabs): Pass a pointer to
         a symbol_matcher_data struct to expand_symtabs_matching
         instead of just the lookup name.
         * c-lang.c, d-lang.c, jv-lang.c, m2-lang.c, objc-lang.c,
         opencl-lang.c, p-lang.c, language.c: Delete field
         la_symbol_name_compare, and replace by NULL for new field
         * symfile.h (struct quick_symbol_functions): Update comment.
