7087,'select' fails for very large arguments to 'threadDelay',Gabriel439,,"The following program crashes GHC with an internal error:

import Control.Concurrent

main = threadDelay 9223372036840001

That seems to be the smallest value that still crashes threadDelay.  The next smallest value works.  Interestingly, the largest value that works happens to be equal to:

((maxBound :: Int) `div` 10^7 - 1) * 10^4

... for whatever that's worth.

If you compile this (with or without optimizations) on ghc-7.4.1, the program crashes with the following error message:

select: Invalid argument
bug: internal error: select failed
    (GHC version 7.4.1 for x86_64_unknown_linux)
