            Bug ID: 24607
           Summary: memory corruption in libLLVMCore [ Metadata.{h|cpp}
           Product: libraries
           Version: 3.6
          Hardware: Sun
                OS: Solaris
            Status: NEW
          Severity: normal
          Priority: P
         Component: Core LLVM classes
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

This is a placeholder bug for a patch I will be submitting very shortly.

There is some memory corruption happening in the overloaded operator::new
and operator::delete for MDNode, MDTuple, MDLocation and MDNodeFwdDecl.

I have a patch for it, and with this patch, the memory corruption is cured.

We have a number of clang and llvm patches for Solaris, and we have every
intention of contributing them to the project. This is just the first of
several bugs with follow-up patches that I will be filing.
