Bug ID: 120199
Summary: ICE in type_dependent_expression_p when using
__builtin_addressof on templated function
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mario.rodriguezb1 at um dot es
Target Milestone: ---
Using __builtin_addressof on a templated function results in an internal
compiler error (ICE) in type_dependent_expression_p, even when the function is
not actually instantiated or used.
If code is slighly change ICE can change, and version where it occurs too.
```
#include <iostream>
template<size_t N>
void kernel1() {
__builtin_addressof(kernel1);
}
```
