        OS/Version: All

          Keywords: miscompilation
          Severity: normal
          Priority: P
         Component: Common Code Generator Code

Part 3 of a long series filed on behalf of Austin English.

Clang also miscompiles dlls/msctf/categorymgr.c from Wine. This results in an
AV during Wine's msctf regression test (see
http://bugs.winehq.org/show_bug.cgi?id=25826). Preprocessed source will be
attached. Not sure what -O levels trigger this; need to get more details from
Austin. Shouldn't be related to the integrated assembler.
