Bug ID: 95192
Summary: [11 Regression] ICE: tree check: expected tree_list,
have error_mark in handle_assume_aligned_attribute, at
c-family/c-attribs.c:2996
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

gcc-11.0.0-alpha20200517 snapshot (g:2b9a271b2d0ba340234a138b7f8289bd7dca2fc5)
ICEs when compiling the following testcase, extracted from
test/SemaCXX/builtin-assume-aligned-tmpl.cpp from the clang 10.0.0 test suite:
template<typename T> __attribute__((assume_aligned(sizeof(int(T()))))) T *f();
void test21() {
void *p = f<void>()
}
% g++-11.0.0 -c iu1wkpbg.cpp
iu1wkpbg.cpp: In substitution of 'template<class T> T* f() [with T = void]':
iu1wkpbg.cpp:3:21: required from here
iu1wkpbg.cpp:1:75: internal compiler error: tree check: expected tree_list,
have error_mark in handle_assume_aligned_attribute, at
c-family/c-attribs.c:2996
1 | template<typename T> __attribute__((assume_aligned(sizeof(int(T())))))
T *f();
