Many attributes that accept integer constant as a parameter call default_conversion for such constants to perform the usual arithmetic conversions. The call to default_conversion is always guarded so as to prevent a NULL_TREE, an IDENTIFIER_NODE, or a FUNCTION_DECL from getting into this function. But the alloc_align attribute was missing the FUNCTION_DECL check, so we were crashing when someone passed a function decl as a parameter to it.Bootstrapped/regtested on x86_64-linux, ok for trunk? 2016-07-28 Marek Polacek <pola...@redhat.com> PR c/71574 * c-common.c (handle_alloc_align_attribute): Also check FUNCTION_DECL. * c-c++-common/pr71574.c: New test.
Ok. Bernd
