Bug ID: 18327
Summary: Compile errors when activating -Wsystem-headers
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
I get errors instead of warnings when -Wsystem-headers are enabled.
Testcase:
#include <cmath>
int main(int argc, char *argv[])
{
return 0;
}
Compile command:
clang++ -std=c++11 -Wall -Wsystem-headers test.cpp
Output (I get a bunch of the same kind):
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/cmath:245:3:
error: constexpr function never produces a constant expression
[-Winvalid-constexpr]
exp(long double __x)
