Bug ID: 89512
Summary: ICE in get_expr_operands, at tree-ssa-operands.c:882
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de

template <typename A>
static const int a = 0;
};
struct B {

static int foo ()
{

}
};
int bar ()
{
int i = B::foo<A> ();
}
$ g++-9-20190224 -c z1.cc
