[Bug gdb/17708] New: GDB segfault when demangling symbol

            Bug ID: 17708
           Summary: GDB segfault when demangling symbol
           Product: gdb
           Version: 7.8
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: sourceware at ca dot sh13.net

The demangler crashes on the following symbol
_ZN5nivenmlIfLi4EfEENS_5ColorIDTmlcvT__EcvT1__EEXT0_EEES3_RKNS1_IS2_XT0_EEE

This is probably a new mangling for the type mentioned in bug 17157 -- the
symbol name from bug 17157 is no longer generated by GCC 4.9.1/Clang 3.5. This
also crashes c++filt.

The type in question is (probably) this one:

    template <typename U>
    auto operator* (const U& rhs) const
        ->     typename cpp0x::enable_if<cpp0x::is_arithmetic<U>::value,
        const Color<decltype (U () * Type ()), Size> >::type

in a type template <typename Type> struct Color {};

--- Comment #1 from sourceware at ca dot sh13.net ---
Or it's the division operator, which is defined equivalently (just replace *
with /)
