            Bug ID: 19820
           Summary: division by std::complex<double> wrong when its module
                    is small
           Product: clang
           Version: 3.4
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

The following code does not produce the correct answer. It should be
(1.e+162,0) and instead one gets (inf,-nan)

#include <iostream>
#include <complex>

int main() {
  std::complex<double> c(1.e-162,0);
  std::cout << 1.0/c << std::endl;
  return 0;
}
