            Bug ID: 23238
           Summary: __cxa_new_handler missing in libc++abi from 3.6
           Product: libc++abi
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

libc++abi from the 3.6.0 tarball is not binary compatible with older versions
and will break the system if installed on OSX.

I noticed this when updating libcxxabi in MacPorts.

libc++abi from 3.5.1 contains the symbol ___cxa_new_handler whereas 3.6.0
contains the C++ mangled symbol __ZSt17__cxa_new_handler instead
