Running rowMedians with parallel = TRUE on certain matrices can crash R session

[StevenMayher]

Describe the bug
I haven't fully deduced the precise nature of the following bug, but it seems that running rowMedians with parallel = TRUE on the matrix generated below crashes my R session:

To Reproduce

library(Rfast)
set.seed(42)

mat = matrix(sample(100000, replace = TRUE), nrow = 1000, ncol = 100)

rowMedians(mat, parallel = TRUE)

Expected behavior

rowMedians(mat, parallel = FALSE)
