Re: [eigen] How to obtain the matrices Q and R of a QR decomposition

[Sebastian Birk <birk@xxxxxxxxxxxxxxxxxxxxx>]

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
