 Bug #: 51146
   Summary: The name clog for a global variable triggers a
segfault inside std::pow
Classification: Unclassified
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: major
  Priority: P3
 Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: alpha...@hotmail.com


Adding a global variable to the code with a name like clog, while using
std::pow on a std::complex triggers a segfault when std::pow is
reached. A simple example ( http://codepad.org/4Ekpgj91 ):

#include 
#include 
#include 

int clog=0;

int main()
{
std::cout<<"test1"< b(1,-1);
std::cout<<"test "<

In case it helps on that side, I've asked a VC++ user to try this code and it
worked perfectly.
