            Bug ID: 16557
           Summary: -fno-exceptions behavior does not match GCC (or,
                    -fcheck-new is not implemented)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

Test case

The attached test case, when compiled with "gcc -fno-exceptions -fcheck-new"
prints nothing and exits with a zero status.  When compiled with llvm/clang 3.3
and ToT (with the same arguments), it segfaults in the member initializer.

Ideally, when using -fno-exceptions, clang would emit code to check the return
value of "new" before calling the constructor, regardless of that operator's
exception specification.
