R Session Crash

[lschneiderbauer]

When certain parameter constraints are violated the whole R session crashes.
(not sure which one exactly, but it came up in one of the use cases).

Needs more investigation.

Reproduces crash:

restrictions <-
  data.frame(site = 1L, vehicle = 2L) |> 
  dplyr::filter(1 == 2)

heumilkr::clarke_wright(
  demand = 203,
  distances = dist(c(1, 67.1)),
  vehicles = data.frame(id = c("5202350330", "5402500381"),
                        caps = c(33, 38), n = c(NA_integer_, NA_integer_)),
  restrictions = restrictions
)

In contrast, this works:

heumilkr::clarke_wright(
  demand = 203,
  distances = dist(c(1, 67.1)),
  vehicles = data.frame(id = c("5202350330", "5402500381"),
                        caps = c(33, 38), n = c(NA_integer_, NA_integer_))
)

I also have irreproducible crashes.
One coincidence: same arguments crash one time, but do not crash another time.
-> hints towards deeper memory issues?
