             Bug #: 54196
           Summary: gcc doesn't find incompatible exception specification
                    for operator
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mib.bugzilla@gmail.com


It look like g++ emit error for regular functions but not for new.  Here is the
example: 
For following test case g++ emit error for foo but not for operator new. 


class bad_alloc 
{ 
  public: 
    bad_alloc() throw() { } 
}; 
struct nothrow_t { }; 
extern const nothrow_t nothrow; 
typedef unsigned long size_t; 
//void* operator new(size_t) noexcept; 
void* operator new(size_t, const nothrow_t&); 

void foo(); 
int main(int argc, char *argv[]) 
{ 
  void* (*pf)(size_t) throw (bad_alloc) = operator new; 
  void* (*pf1)() throw (bad_alloc) = foo; 
}
