Bug ID: 24247
Summary: Error message for labeled-statement inside constexpr
function body
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++14
Assignee: unassignedclangb...@nondot.org
Reporter: anders.granlun...@gmail.com
CC: llvmbugs@cs.uiuc.edu
Classification: Unclassified
Consider the following program (prog.cc):
constexpr void f() { x: ; }
int main() {}
It is well-formed. Observe that [dcl.constexpr]/4
(http://eel.is/c++draft/dcl.dcl#dcl.constexpr-3) does forbid goto statements,
but not labeled-statements.
Compile it with the following command-line:
clang++ prog.cc -std=c++14 -pedantic-errors
The following error message is given:
prog.cc:1:22: error: statement not allowed in constexpr function
constexpr void f() { x: ; }
^
1 error generated.
Expected behaviour is to get no error messages since the program is
well-formed.
I tired it with gcc also, and it gives no error message.
