Bug ID: 106976
Summary: internal compiler error: tree check: expected class
'type', have 'exceptional' (error_mark) in
override_type_for_decl_p, at dwarf2out.cc:24345
Product: gcc
Version: 12.2.1
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
For this invalid code:
struct S{
constexpr static auto s = requires { []; };
};
Without -g we get an unhelpful error:
$ g++-11 -std=c++20 -g -c ice.C
ice.C:2:25: error: storage size of 'S::s' isn't known
2 | constexpr static auto s = requires { []; };
| ^
But it ICEs with -g
ice.C:1:8: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in override_type_for_decl_p, at dwarf2out.cc:24345
