[datatable-help] Segfault using data.table 1.9.4 with multtest 2.24.0 on R 3.2.2

[Tom Harrop]

Hello all,

I'm running into a segfault using data.table with the multtest package:

Am I doing something wrong? The following executes without problems 
(otherwise I would be contacting the multtest authors!):

> > library(data.table)
> data.table 1.9.4  For help type: ?data.table
> *** NB: by=.EACHI is now explicit. See README to restore previous 
> behaviour.
> > p <- data.table(pval = rnorm(100, 0.5, 0.1))
> > multtest::mt.rawp2adjp(p$pval, proc = "BH", alpha = 0.1)

My sessionInfo is at the end. Please let me know if any more information 
is required.

Thanks for reading,

Tom
