Bug ID: 107056
Summary: [11/12/13 Regression] ICE: unexpected expression
'(unsigned int)((const char*)"")' of kind
implicit_conv_expr
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gscfq@t-online.de
Target Milestone: ---
Started with r11 between 20201122 and 20201129,
test file derived from g++.dg/warn/Wunused-17.C :
$ cat z1.cc
int memory_consumption(const int &t) { return sizeof(t); }
int s;
int g() { return memory_consumption(s); }
template <int> struct X { static const int s = 2; };
template <typename T> int f() {
const unsigned int dim = "";
return X<dim>::s;
}
template int f<int>();
static int i;
template <typename> int h() { return i; }
$ gcc-13-20220925 -c z1.cc -Wfloat-conversion
