Hi, when I compile that QR decomposition code using SSE extensions like with this optimization parameters -O3 -mtune=core2 -mfpmath=sse -msse4.1 the computation of the QR decomposition causes an segmentation fault, which I tracked back to the source line return pmul(a, pconj(b)); in the function template<> struct conj_helper<Packet1cd, Packet1cd, false,true> in SSE/Complex.h. Is this an error in Eigen or is it me again doing weird stuff? ;-) Sebastian
