Bug ID: 122092
Summary: ICE: tree check: did not expect class ‘type’, have

Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

Input:
#include <iostream>
struct Base {
unsigned int *intarray;
};
template <typename T>
struct Sub : public Base {
bool Get(int i) {
return (Base::intarray[++i] == 0);
}
};
int main() {
Sub<int> s;
s.intarray = new unsigned int[10];
s.Get(0);
delete[] s.intarray;
return 0;
}
Output:
test.cpp:11:31: internal compiler error: tree check: did not expect class
‘type’, have ‘type’ (record_type) in contains_placeholder_p, at tree.cc:4085
11 | return (Base::intarray[++i] == 0);
