R session crashes when assigning using by = .EACHI

The current snippet crashes my r session when it gets to the last statement

dt <- data.table(id = c("A", "A", "B", "B", "C"),
                 start = structure(c(12894, 15706, 14153, 14533, 14539), class = "Date"),
                 end = structure(c(15705, 15763, 14532, 14578, NA_real_), class = "Date"),
                 key = "id")

sample <- c("A", "B")

dt[sample,
   temp := c(start[-1L] - 1L, NA_real_),
   by = .EACHI]

Can you reproduce it?

Thanks a bunch for the minimal example! Reproducible. Added to 1.9.4 milestone.

[nigmastar]

my pleasure! Just to be precise, it also happens without any assignment.

dt[sample, c(start[-1L] - 1L, NA_real_), by = .EACHI]

Thanks again, Michele. Reproducible as well.
