Bug ID: 15934
Summary: failed formatted input overwrites output value
Product: libc++
Version: 3.2
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs

Hello!
Here is a small test:
#include <sstream>
#include <iostream>
int main()
{
std::istringstream iss("-a");
unsigned i = 12345;
iss >> i;
std::cout << i << std::endl;
return 0;
}
When building with clang/libc++ I got the following output:
$ clang++ -stdlib=libc++ a.cpp
$ ./a.out
0
$ clang -v
Apple LLVM version 4.2 (clang-425.0.27) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.3.0
Thread model: posix
$ uname -a
Darwin hostname 12.3.0 Darwin Kernel Version 12.3.0: Sun Jan 6 22:37:10 PST
2013; root:xnu-2050.22.13~1/RELEASE_X86_64 x86_64
In C++ standard (C++03) I can see 22.2.2.1.2p1 [lib.facet.num.get.virtuals]:
"If an error occurs, val is unchanged; otherwise it is set to the resulting
value."
