           Summary: clang -fsyntax-only runs forever on provided input
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: kremenek at cs.stanford.edu
                CC: llvmbugs at cs.uiuc.edu, snaroff at apple.com

I've attached an input file that causes "clang -fsyntax-only" to not terminate.
 The file was the intermediate byproduct of running Delta Debugging to generate
a reduced test case for a bug I was encountering in the static analyzer.  I
cannot isolate that bug, however, because the semantic analyzer never finishes
processing the file (which I doubt is valid source code).  I don't know if I
can make the input file more reduced (or legible); it's a reduced code snippet
from a truly hairy function from PCRE.
