    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: so.townsend@gmail.com

Example of problem

Creating a class with a constructor that calls another construct with a non
existent symbol yields a segfault and no compile time errors or warnings.

Both -std=C++0x and standard compilation have the same issue.

that doesn't call a constructor, it declares an object called a, so is
identical to:

Foo()
{
  Foo a;
}

which causes an infinite recursion

well, sorry, it does call a constructor, but it calls the same one (the default
cosntructor) 

it doesn't call the other constructor "with a non-existent symbol"
