I was trying to build an LLVM for one of my machines from a much more powerful machine and wanted to add the flags that `-march=native' enables for that processor but I was unaware that `-m128bit-long-double' was enabled by default already. I accidentally added `-m96bit-long-double' myself instead of `-m128bit-long-double', running g++ with both `-m64' and `-m96bit-long-double' caused the ICE.
