Hi, I have build LLVM 4 with -DLLVM_USE_INTEL_JITEVENTS=true, which works fine on Linux, but on Windows it crashes in lli. The problem occurs at the access of the DebugObj.getData().data() in IntelJITEventListener.cpp, with DebugObj being a struct at NULL. Has someone here experience with the inteljiteventlistener activated on Windows? Thanks, Florian
