Bug ID: 89187
Summary: ICE in initialize_argument_information, at
calls.c:2023
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: s390x-linux-gnu
Following code is causing ICE:
$ cat ice.C
template <typename a, int b> struct c {
typedef a __attribute__((vector_size(b))) d;
};
template <typename a, int b> using e = typename c<a, b>::d;
template <typename a> using f = e<a, 4>;
struct g {
g(f<int> h) : i{h[3]} {}
g j() { return i; }
f<int> i;
};
struct {
g k();
} l;
class m {
void n() const;
};
void m::n() const { l.k().j(); }
