R 2.12.0 beta (r53110) fails make check on Ubuntu hardy

Hi!

we observe a failing make check for reg-tests-1b.R with r53110 and since at least r53056
with the failing lines being

[...]

## found from fallback test in slam 0.1-15
x <- matrix(c(1, 0, NA, 1), 2, 2)
y <- matrix(c(1, 0, 0, 2, 1, 0), 3, 2)
(z <- tcrossprod(x, y))

    [,1] [,2] [,3]
[1,]   NA   NA    0
[2,]    2    1    0

stopifnot(identical(z, x %*% t(y)))

Error: identical(z, x %*% t(y)) is not TRUE
Execution halted


In a fresh R session the results are
x %*% t(y)
    [,1] [,2] [,3]
[1,]   NA   NA   NA
[2,]    2    1    0

(z <- tcrossprod(x, y))
    [,1] [,2] [,3]
[1,]   NA   NA    0
[2,]    2    1    0

Regards,

 Matthias
