What OS? Is this on a vm? I7-avx is the instruction family. I5 will be ok. Certain vms break handling avx register saves. <span></span><br><br>On Thursday, April 24, 2014, Daniel Fischer <<a href="mailto:daniel.is.fischer@googlemail.com">daniel.is.fischer@googlemail.com</a>> wrote:<br>

You are using a new version of LLVM that hasn't been tested yet!<br>
We will try though...<br>

I suspect that the LLVM backend thinks I have a different version than I<br>

But my CPU is a Core i5, not i7.<br>

Can somebody confirm or deny that that may be the cause?<br>
