            Bug ID: 21683
           Summary: SimpleReference leak in SimpleDefinedAtom
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: devlists at shadowlab.org
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

When linking, SimpleDefinedAtom are allocated using a llvm::bumpPtr (at least
for Mach-O linking).

The SimpleDefinedAtom destructor is never called, and so its
std::vector<SimpleReference> member is never destroyed.

After linking clang, it results in a leaks of more than 177000 SimpleReference
objects (65MB).
