Instead I can reproduce similar problem as pointed by Feng:

compiler::enableJIT(1)
foo <- function(){
    browser()
    cat("here\n")
    cat("here\n")
}

foo()

and then "n RET". Everything is skipped. 

If this is the intended behavior then a very loud note would be really
welcome in the "compile" help page.

Thanks, 
Vitalie.
