Description
**Describe the bug**
Using Catch2 with `REQUIRE(std::indirect(42) == 42)` triggers a recursive constraint satisfaction error with gcc and clang.
`error: satisfaction of atomic constraint 'requires(const _Tp& __t, const _Up& __u) {__t == __u;} [with _Tp = _Tp; _Up = _Up]' depends on itself`
**Expected behavior**
`REQUIRE(std::indirect(42) == 42)` should compile and pass.
**Reproduction steps**
Build this snippet with x86-64 gcc trunk and -std=c++26
```
#include
#include
TEST_CASE( "std::indirect(42) compares equal to 42" ) {
REQUIRE(std::indirect(42) == 42);
}
```
**Platform information:**
- OS: Compiler Explorer
- Compiler+version: x86-64 gcc trunk and x86-64 clang trunk
- Catch version: Tested with trunk and 3.0.1
