i5 and invalid instructions



Hello all,

Just got my new work laptop, a Dell with an Intel i5-3320m processor. The 
first thing I did after installing NetBSD was compile a new kernel and 
distribution, with the cpuflags package installed.

cpuflags activates -march=native, which in my case enables everything up to 
SSE4, AVX and all those other newfangled optimisations new processors have. 
However, after installing the distribution, every command I try to run core-
dumps with "Illegal instruction"...

I'm still investigating what exactly is going on, and most importantly, what 
causes the problem, and I'm not sure whether this is a NetBSD or a gcc 
problem, but I just wanted to ask, has anyone seen this type of thing before? 
(A quick web search seems to suggest not, but you never know...)

Thanks,

  Jaap
