spatstat integer overflow error in Kcross and crosspairs

I'm working with spatstat 2.3-4 in R 4.1.0 on a 64bit windows 10 pro machine. Recently I ran into the integer-overflow error while using Kcross with a large number of points (i.e. the number of combination exceeded .Machine$integer.max). For example:

W <- as.owin(list(xrange = c(688.512, 17879.746) , yrange = c(-27996.842, -7759.813))) 
cells1 <- runifpoint(n = 8062, win = W)
cells2 <- runifpoint(n = 1768988, win = W) 
cells3 <- superimpose(tumor = cells1 , bcell = cells2)
Kcross(cells3 , r = seq(0,200,by=5) , "tumor" , "bcell" , correction="none") # error
# Error in if (nXY <= 1024) { : missing value where TRUE/FALSE needed 
# In addition: Warning message: In nX * nY : NAs produced by integer overflow 
8062 * 1768988 > .Machine$integer.max
# [1] TRUE

After a lot of struggling I realized that the error comes from this part of crosspairs:

if (spatstat.options("crosspairs.newcode")) {
      nXY <- nX * nY
      if (nXY <= 1024) {
          nsize <- 1024
      }

I could "fix" the error by changing spatstat options: spatstat.options("crosspairs.newcode" = FALSE).

Is this the way to deal with the error?

UPDATE: As Adrian.Baddeley answered below, there is now a new spatstat.geom version on GitHub (currently: v2.4.-0.029) in which the bug is fixed. The new version works fine without the change of the options.

Solution

The bug is fixed in the development version of spatstat.geom available at the GitHub repository
