Bug ID: 21018
Summary: "Dead assignment" false positive - ignores access
through reference
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
For this code (unused.cpp):
#include <iostream>
int main()
{
int x = 1;
int& ref = x;
std::cout << ref << std::endl;
x = 2;
std::cout << ref << std::endl;
return 0;
}
I get following output from scan-build:
unused.cpp:9:5: warning: Value stored to 'x' is never read
x = 2;
^ ~
1 warning generated.
The value is obviously read, as second cout<<ref prints out 2, as expected.
My "clang++ --version":
Ubuntu clang version 3.5-1ubuntu1 (trunk) (based on LLVM 3.5)
Target: x86_64-pc-linux-gnu
Thread model: posix
