Hi!If lookup_name_fuzzy finds an exact match with a macro, it later in the dtor uses node->value.macro->line in libcpp. The problem is that for builtin macros node->value.macro contains garbage, we use node->value.builtin union member in those cases instead. It doesn't make any sense to look up location of a builtin macro definition anyway, those are very special entities. So, this patch just ignores those, because we can't do anything useful with them. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2018-01-02 Jakub Jelinek <ja...@redhat.com> PR preprocessor/83602 * name-lookup.c (lookup_name_fuzzy): Don't use macro_use_before_def for builtin macros. * g++.dg/cpp/pr83602.C: New test.
