Bug ID: 98644
Summary: [concepts] ICE in satisfaction_value, at
cp/constraint.cc:2825
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: arthur.j.odwyer at gmail dot com
Target Milestone: ---
// https://godbolt.org/z/qh1zos
template<class T> concept Signed = bool(T(1));
static_assert(Signed<int*>);
Compile with "-std=c++20":
<source>:2:28: internal compiler error: in satisfaction_value, at
cp/constraint.cc:2825
2 | static_assert(Signed<int*>);

Another very similar ICE, even though the stack trace is different:
// https://godbolt.org/z/rPn6vd
bool Signed = requires { requires bool((char *)1); };
<source>:1:35: internal compiler error: in satisfaction_value, at
cp/constraint.cc:2825
