Bug ID: 88348
Summary: ICE in pp_cxx_unqualified_id when handling pointer to
pointer to member
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhouzhouyi at gmail dot com
Target Milestone: ---
g++ from git ICE when compiling following program because of incorrect
handling pointer to pointer to member
---
void* operator new (__SIZE_TYPE__, void *p) { return p; }
int i;
struct Z {
void f(int = 0) const;
};
template <class T> struct helper {};
typedef void (Z::**QF)(int) const;
template <class T> void check1( helper<new QF> * ) { }
---
