Bug #: 14253
Summary: No unused warning for variables of non-trivial types
Product: clang
Version: trunk
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Clang warns about unused variables e.g. of type 'int', but not 'std::string' :
$ cat a.cpp
#include <string>
void foo()
{
int i;
std::string s;
}
$ clang++ -Wall -Wunused -c a.cpp
a.cpp:5:9: warning: unused variable 'i' [-Wunused-variable]
int i;
^
1 warning generated.
In the function 's' is apparently unused too, but the compiler cannot tell it.
