--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. Bisection points to r210262:
PR c/50459
c-family/
* c-common.c (check_user_alignment): Return -1 if alignment is error
node.
(handle_aligned_attribute): Don't call default_conversion on
FUNCTION_DECLs.
(handle_vector_size_attribute): Likewise.
(handle_tm_wrap_attribute): Handle case when wrap_decl is error node.
(handle_sentinel_attribute): Call default_conversion and allow even
integral types as an argument.
c/
* c-parser.c (c_parser_attributes): Parse the arguments as an
expression-list if the attribute takes identifier.
testsuite/
* c-c++-common/attributes-1.c: Move test line to a new test.
* c-c++-common/attributes-2.c: New test.
* c-c++-common/pr50459.c: New test.
* c-c++-common/pr59280.c: Add "undeclared" to dg-error.
* gcc.dg/nonnull-2.c: Likewise.
* gcc.dg/pr55570.c: Modify dg-error.
* gcc.dg/tm/wrap-2.c: Likewise.
Prior to that GCC rejected the test case with:
error: constructor priorities must be integers from 0 to 65535 inclusive
void g () __attribute__ ((constructor(f)));
