             Bug #: 12888
           Summary: -fno-rtti should disable typeid
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: mimomorin at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

It seems that, with -fno-rtti compiler option, `typeid(int)` becomes something
like `*static_cast<type_info*>(0)`. So, `typeid` is useless when compiling with

-fno-rtti should disable typeid.
