https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105912 --- Comment #6 from CVS Commits --- The releases/gcc-12 branch has been updated by Patrick Palka : https://gcc.gnu.org/g:a074ae297d5dbd69e03c6c30f9cb7720685fdb62 commit r12-8606-ga074ae297d5dbd69e03c6c30f9cb7720685fdb62 Author: Patrick Palka Date: Thu Jul 21 12:59:44 2022 -0400 c++: non-dependent call to consteval operator [PR105912] Here we're crashing when substituting a non-dependent call to a consteval operator, whose CALL_EXPR_OPERATOR_SYNTAX flag we try to propagate to the result, but the result isn't a CALL_EXPR since the selected function is consteval. This patch fixes this by checking the result of extract_call_expr accordingly. (Note that we can't check DECL_IMMEDIATE_FUNCTION_P here because we don't know which function was selected by overload resolution from here.) PR c++/105912 gcc/cp/ChangeLog: * call.cc (extract_call_expr): Return a NULL_TREE on failure instead of asserting. * pt.cc (tsubst_copy_and_build) : Guard against NULL_TREE extract_call_expr result. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/consteval31.C: New test. (cherry picked from commit f70c18524221dcefa6cd26cee7b55503181bd912)

--- Comment #1 from Luke Dalessandro ---
Somewhat reduced testcase:
template struct A {};
template struct B {};
template
static consteval auto operator~(A) -> B {
return {};
}
A<'i'> i;
template
auto test() -> bool {
auto ii = ~i; // ICE HERE
return true;
}
int main()
{
bool i = test();
}
