Matrix inner product seems to crash R2.2.1 on a 64bit arch. More precisely, the crash happens atleast if the matrix is non-square. The bug can be reproduced (atleast here) with
bash$ bin/R > X<-matrix(data=0,nrow=100,ncol=10); > mat<-X%*%t(X); Illegal instruction bash$ The crash doesnt happen if the matrix is specified square, e.g. 10x10. The underlying OS was Linux version 2.6.12-xeon-csl3 ([EMAIL PROTECTED]) (gcc version 3.4.5 20050809 (prerelease) (Ubuntu 3.4.4-6ubuntu8)) #1 SMP Wed Feb 22 18:34:17 EET 2006 and its running on Intel(R) Xeon(TM) MP CPU 3.66GHz. I configured R from the source tar.gz myself; each phase of "./configure --with-x=no ; make ; make install" passed without aborting on any errors.
