我用LLVM已經存在的通行證，沒有問題，直到我試圖使用MemDepPrinter.cpp：http://llvm.org/doxygen/MemDepPrinter_8cpp_source.html。我得到了以下段錯誤：llvm MemDepPrinter segfault
llvm[0]: Compiling MyMemDepPrinter.cpp for Release+Asserts build (PIC)
llvm[0]: Linking Release+Asserts Loadable Module MyMemDepPrinter.so
WARNING: You're attempting to print out a bitcode file.
This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.

當我在GDB模式下運行它，我得到：
Program received signal SIGSEGV, Segmentation fault.

作爲更新，線路問題是：
MDA.getNonLocalPointerDependency(Loc, true, LI->getParent(), NLDI);
，而不是4個參數是問題。所有這些都已定義，我可以使用它們。我沒有segfault，如果我消除線。
我認爲這個問題是在註釋中定義：
FIXME: Handle atomic/volatile loads.
請告訴我，我怎麼能解決這個問題（也許把一個條件，以避免原子/揮發性負載），或者如果通過正常工作對你如果是這樣，你如何使用它。
謝謝！
