Summary: [9 Regression] ICE in dwarf2out_abstract_function, at
dwarf2out.c:22479 since r264943
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: ebotcazou at gcc dot gnu.org
Target Milestone: ---
Following causes ICE:
$ cat turbo.ii
struct a {
virtual ~a();
};
template <typename b> class c {
public:
class d {
public:
d(c);
b *operator->();
};
};
int e, f;
class g {
public:
class h {
public:
virtual void j(g &, int &, bool) = 0;
};
c<h> k();
int *l();
int *m();
};
int *g::l() try {
for (c<h>::d i(k());;)
i->j(*this, e, true);
} catch (int) {
return 0;
}
int *g::m() try {
for (c<h>::d i(k());;)
i->j(*this, f, false);
} catch (int) {
return 0;
}
struct n : a, g::h {
void o();
void j(g &, int &, bool) { o(); }
};
$ g++ -O2 -g turbo.ii -c -m32 -fPIC -Wall
