Bug ID: 37830
Summary: ICE with typeof applied to template parameter
dependent expression
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: zhong...@pku.org.cn
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
The code is as follow:
# 1 "foo.cc"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "foo.cc"
template<typename T>
void Bar(T t, typeof(T() - T()) s) {}
int main() {
char* a;
int i;
Bar(a, i);
return 0;
}
clang++ produces no error message, when it compiles the above code. gcc++
produces an error message. In particular, it warns that "void Bar(T t,
typeof(T() - T()) s) {}" shall be changed to "void Bar(T t, decltype(T() - T())
s) {}".
Shall clang++ present similar error messages?
