Already reported in the mailing list: http://listengine.tuxfamily.org/lists.tuxfamily.org/eigen/2011/01/msg00010.html I attach the patch here, but as said in the list, please someone take a look at the handling of __PIC__ to make sure it's OK. Regards, JL

Some additional info on this error: It seems to happen when both a library A and an executable B use Eigen and B is also linked against A.

Sorry for the time taken to reply to this, and thanks for the report and patch. We've just been busy. Gael says he'll review your patch ASAP.

patch pushed. Indeed the issue of PIC and the cpuid instr. using the ebx register is for the i386 target only. That does not explain the segfault though.
