Bug ID: 38227
Summary: constexpr function call is not noexcept
Product: clang
Version: 6.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: andrey.vih...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Compiling the following code:
constexpr int f()
{
return 0;
}
static_assert(noexcept(f()), "f() should be noexcept");
with "clang++ -std=c++11 -c x.cpp" gives:
x.cpp:6:1: error: static_assert failed due to requirement 'noexcept(f())' "f()
should be noexcept"
static_assert(noexcept(f()), "f() should be noexcept");
^ ~~~~~~~~~~~~~
1 error generated.
According to https://en.cppreference.com/w/cpp/language/noexcept, it would
appear the assert should succeed, because "f()" is a constant expression. GCC
8.1 accepts the code.
