[BUG] Reporting example where new compiler failed

I was running a model that I was fitting for teaching purposes when I got the message quoted below. I've pasted the code that generated the data together with the model call in brms that produced the error:

When you compile models, you are also contributing to development of the NEXT Stan compiler. In this version of rstan, we compile your model as usual, but also test our new compiler on your syntactically correct model. In this case, the new compiler did not work like we hoped. By filing an issue at https://github.com/stan-dev/stanc3/issues with your model or a minimal example that shows this warning you will be contributing valuable information to Stan and ensuring your models continue working. Thank you!

library(fabricatr)

set.seed(20231012)
d <- fabricate(
  PartID = add_level(N = 30, 
                     age_yrs = round(runif(N, min = 18, max = 40)),
                     age_of_onset = round(age_yrs - (1+rexp(N, rate = 0.6))),
                     part_offset = round(rnorm(N, 0, 1), digits = 2)),
  ItemID = add_level(N = 100, 
                     log_frequency = round(runif(N, 1, 6), digits = 1),
                     item_offset = round(rnorm(N, 0, 0.6), digits = 2),
                     nest = FALSE),
  obs = cross_levels(
    by = join_using(PartID, ItemID)
  )
)

d$LOE <- d$age_yrs-d$age_of_onset

Int <- 0.75
d$ACC <- rbinom(3000, 1, plogis(Int + 0.3*d$LOE + 0.4*d$log_frequency + d$item_offset + d$part_offset))

When I fit the following model, it works in the current version of brms, but throws the message above:

library(brms)
fit<- brm(ACC ~ LOE * log_frequency + (1|PartID) + (1|ItemID),
             data = d,
             family = bernoulli(),
             prior = c(
               prior(normal(0, 1.5), class = "Intercept"),
               prior(normal(0, 1), class = "b"),
               prior(exponential(1), class = "sd")
             ))
