--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Most likely it is trying to print:
```
<source>:8:34: warning: inline function 'typename e<(! c<
<template-parameter-1-1> >::d)>::g bar(_Tp) [with _Tp = int; typename e<(! c<
<template-parameter-1-1> >::d)>::g = void]' used but never defined
 inline typename e<!c<_Tp>::d>::g bar(_Tp);
                                  ^~~

```

But it fails because of the conversion from an enum to bool.
