R devel - Mar 2012 - enableJIT() prohibits usual R debugging

Hi, 

Browser doesn't work properly with the compiler enabled. It might be
intended behavior, but it's not documented.


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



Browser doesn't stop, and I am getting:
> foo()
Called from: foo()
Browse[1]> here

Thanks,

I can't reproduce this in either 2.14.1 or R-devel.
