I'm currently on a MacBook with OSX 10.9.5, and all three examples give me *{... lots of digits...}*. $ ghci --version The Glorious Glasgow Haskell Compilation System, version 7.8.3 On Fri, Oct 17, 2014 at 11:21 AM, Alexander Vieth wrote:

Interesting. This is reproducible on my machine (OSX 10.7.5), with an older GHC:

$ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.6.3

Running ghci under OSX I am seeing the following behavior:

Prelude> 2^750000 {... lots of digits...}

Prelude> 2^760000 Segmentation Fault: 11

Prelude> 2^770000 Bus Error: 10

and I'm curious why this happens.

More details:

$ ghci --version The Glorious Glasgow Haskell Compilation System, version 7.8.3

I'm using the 64-bit version of the Haskell Platform (x86_64-darwin-7.8.3).
