Hello,
With R 3.2.2 built from r in statistics.scm (guix 0.9.0), I'm seeing a
segfault when eigen is called with a matrix over some size. I can
trigger the error with the following code [1]:
> M <- 50
> N <- 500
> eigen(crossprod(matrix(rnorm(M * N), M, N)))
*** caught segfault ***
address 0xfb0, cause 'memory not mapped'
Traceback:
1: eigen(crossprod(matrix(rnorm(M * N), M, N)))
Can others reproduce this?
Thanks.
[1] This is a down-sized version of the snippet from an ATLAS bug report
in 2011 for a similar error with R 2.14.
