Summary: ICE in gen_formal_parameter_die
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Assignee: unassigned at gcc dot gnu.org

I've just built gcc from svn r224315 on x86_64-unknown-linux-gnu. I get:
$ cat x.c
void f(int p) {}
int g() {
void f();
g();
return 0;
}
$ ~/gcc/local/bin/gcc -g -O3 -c x.c
x.c: In function 'f':
x.c:6:1: internal compiler error: in gen_formal_parameter_die, at
dwarf2out.c:17995
}
