Bug ID: 118368
Summary: 'baselink' not supported by dump_type<type error>
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Take:
```
template<typename T, typename T1=int>
struct holder
{
template<typename F> struct fn {};
struct t2 : holder<T>::template fn<T> {};
};
template<>
struct holder<int, int>
{
template<typename F>
void fn();
};
holder<int, float>::t2 holder_1;
```
GCC gives:
```
<source>: In instantiation of 'struct holder<int, float>::t2':
<source>:16:24: required from here
16 | holder<int, float>::t2 holder_1;
| ^~~~~~~~
<source>:7:10: error: 'typename holder<int, int>::fn' names ''baselink' not
supported by dump_type<type error>', which is not a class template
7 | struct t2 : holder<T>::template fn<T> {}; // fail
| ^~
```
Having an error message is correct but we get "'baselink' not supported by
dump_type<type error>" which is not something which we should get.
Found while looking into PR 118347.
