Bug#907621: llvm-3.8: Compiler Error for wrong conversion in LLVM/include/llvm/IR/ValueMap.h while building KLEE

[Kaipeng Zeng]

Package: llvm-3.8
Version: 1:3.8.1-24
Severity: normal

Dear Maintainer,

    When i was building KLEE follow the documentation:
    http://klee.github.io/build-llvm38/
    I got the compiler error:
    /usr/lib/llvm-3.8/include/llvm/IR/ValueMap.h:102:31: error: cannot convert ‘const std::unique_ptr<llvm::DenseMap<const llvm::Metadata*, llvm::TrackingMDRef> >’ to ‘bool’ in return
    bool hasMD() const { return MDMap; }
    It seems to be the same error that has been discussed:
    https://github.com/digego/extempore/issues/318
    and has been fixed:      
    https://github.com/digego/extempore/pull/322/commits
