Bug ID: 117158
Summary: ICE with array access inside a template with a base
class
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Take:
```
struct Base
{
unsigned int *intarray;
};
template <typename T> struct Sub : public Base
{
bool Get(int i)
{
return (Base::intarray[++i] == 0);
}
};
```
This ICEs with:
```
<source>: In member function 'bool Sub<T>::Get(int)':
<source>:10:35: internal compiler error: tree check: did not expect class
'type', have 'type' (record_type) in contains_placeholder_p, at tree.cc:4119
10 | return (Base::intarray[++i] == 0);
