Status: UNCONFIRMED
Keywords: error-recovery, ice-on-invalid-code
Severity: normal
Priority: P3

Target Milestone: ---
g++-10.0.0-alpha20191124 snapshot (r278660) ICEs when compiling the following
testcase reduced from test/SemaCXX/builtin-ptrtomember-overload-1.cpp from the
clang 9.0.0 test suite:
struct A {};
struct E {};
struct R {
operator E*();
};
struct S {
operator E*();
};
struct B1 : R, S {
operator A*();
};
void foo1(B1 b1, int E::* pmf) {
int i = b1->*pmf;
}
% g++-10.0.0-alpha20191124 -c gmnbcjli.cpp
gmnbcjli.cpp: In function 'void foo1(B1, int E::*)':
gmnbcjli.cpp:17:22: internal compiler error: Segmentation fault
