The full error in debug builds is:
```
issue24246.d(34): Error: CTFE internal error: literal `TextStyle`
---
ERROR: This is a compiler bug.
Please report it via https://issues.dlang.org/enter_bug.cgi
with, preferably, a reduced, reproducible example and the information below.
DustMite (https://github.com/CyberShadow/DustMite/wiki) can help with the
reduction.

To work around, you're missing parentheses in the constructor call.

```
auto opBinary(string op)(ubyte other)
{
    return other ? TextStyle() : this;
}
```

Proper reduction of the test case.

auto f24246()
{
    return 1;
}

auto f24246(int i)
{
    return true ? int : i;
}

struct S24246
{
    int field;
}

enum ice24246 = S24246(f24246.f24246);

--- Comment #5 from Iain Buclaw <ibuclaw@gdcproject.org> ---
Confirmed issue. As the following issues an error:
---
auto f24246(int i)
{
    return int; // Error: type `int` is not an expression
}
---

That it's in a conditional expression should not prevent the same error from being given.
