           Summary: AsmStmt should not use SmallVector
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: AST
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: kremenek at apple.com
                CC: llvmbugs at cs.uiuc.edu

AsmStmt uses SmallVector, which can allocate memory using 'malloc()'.  This can
lead to memory leaks when we use the BumpPtrAllocator to allocate AST nodes and
we do not call the destructor of AsmStmt objects.

Fix: AsmStmt should allocate all memory it uses with the allocator associated
with ASTContext.
