SIGABRT during Luxmark 3.1 execution

[haonanya]

I am copying https://github.com/KhronosGroup/SPIRV-LLVM-Translator/issues/404 to LuxMark repo. Luxmark crashed on std::stringstream destructor https://github.com/KhronosGroup/SPIRV-LLVM-Translator/blob/llvm_release_110/lib/SPIRV/OCLToSPIRV.cpp#LL321C7-L323C24). The std::stringstream usage is right, it failed with "vload3" string process but passed with "vload2". Dumped LLVM IR could be translated using llvm-spirv and opencl kernel compiled with ocloc. We suspect problems are with Luxmark itself and maybe Luxmark binary overwrites some functions from libstdc++.
