           Summary: multiple typeinfo name
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen
        AssignedTo: unassignedclangbugs at nondot.org

pes delta-2006.08.03$ g++ -D_REENTRANT -I./source/common -I./source/i18n
-I./source/tools/toolutil -I./source/tools/ctestfw -D'U_TOPSRCDIR="../../"'

N6icu_4613DecimalFormatE
                 U _ZTIN6icu_4613DecimalFormatE

Note that with clang++ the typeinfo name is there twice. This causes problems
for typeid as in this example (derived from icu testcase):

typeid(*nf) != typeid(DecimalFormat)

where each is one instance of the _ZTSN6icu_4613DecimalFormatE.

This cannot be reproduced with a flat C++ file. The attached directory
structure must be preserved. To reproduce untar the source.tgz and invoke the
command line as in above.
