More precision problems in testing with Intel compilers
The Intel compiled version also fails the below test:
> ###------------ Very big and very small
> umach <- unlist(.Machine)[paste("double.x", c("min","max"), sep='')]
> xmin <- umach[1]
> xmax <- umach[2]
> tx <- unique(outer(-1:1,c(.1,1e-3,1e-7)))# 7 values (out of 9)
> tx <- unique(sort(c(outer(umach,1+tx))))# 11 values
