Issue with gof() in ergm.multi_0.3.0-4214 – ergm.multi crashes R

[benrosche]

Dear Pavel,

As discussed at Sunbelt 2025, I'm following up with a reproducible example showing how ergm.multi crashes when using gof() with version ergm.multi_0.3.0-4214. The issue occurs with the current ergm.multi version and doesn't seem related to the other package version I have where constraint=~outdegree works. The issue seems specific to my network object, as it doesn't occur with data("Goeyvaerts"). You can download the network object here

The following code crashes R on my end:
`
library(ergm)
library(ergm.multi)

g <- readRDS("Rosche.rds")

gof.ergm <- gof(Networks(g) ~ N(~mutual, ~log(n)), coef = c(0, 0), verbose = TRUE, control = control.gof.formula(nsim = 10))
`
I'd really appreciate any insight you might have into what's going wrong.
Best wishes, Ben
