I'm running R 1.8.1 on both Linux and OS X compiled with gcc 3.2.2 and 3.3, respectively. The following call seems to freeze the interpreter on both systems:
> chisq.test(matrix(c(233, 580104, 3776, 5786104), 2, 2), simulate.p.value=TRUE)
By freeze, I mean, the function call never returns (running > 10 hours so far), the process is unresponsive to SIGINT (but I call kill it with TERM), and the process still consumes cycles on the CPU.
Browsing through the code, it seems to be getting stuck on the C call to "chisqsim" .

debug: tmp <- .C("chisqsim", as.integer(nr), as.integer(nc), as.integer(sr),
as.integer(sc), as.integer(n), as.integer(B), as.double(E),
integer(nr * nc), double(n + 1), integer(nc), results = double(B),
PACKAGE = "ctest")

Has anyone seen this, or know what may be causing it?
Thanks, Jeff
