It might be (provided that this version of GraphWriter is in the 
release_32 branch of LLVM).  I didn't investigate the details closely.

Vishruth, if you see the error in the release_32 branch on your system, 
can you file a bug report for it?  Fixing a warning like this is low 
priority as it is easy to work around, but we should have a bug report 
to track it.
