R Session aborted when calculating a buffer from a vector

[Julian090601]

Hi,

I have encountered some strange behaviour when calculating a buffer from a vector.

In R version 4.3.1, if the buffer size is larger than 54 metres, the session aborts immediately. However, when I do the same in R version 4.2.3, everything works fine. I have tested on several machines and always come up with the same result.

I have attached the polygon where the error occurs. I have checked the geometry and the crs but I cannot see any problems with them.

terra version: 1.7.55

Krycklan_2015_poly.zip

Thanks. I see that this works

library(terra)
v <- vect("Krycklan_2015_poly.shp")
b <- buffer(v, 75)

But that this crashes R

b <- buffer(v, 100)

This example now works. I am not sure why it failed before.
