Button Printf Callback Fails

The version was 0.12 (not listed as an option).
If I include any call to printf (from Text.Printf) within a button callback, I get a "gtk2hs_closure_marshal: uncaught exception" and the program terminates. The failure does not seem to happen with other non-button callbacks and it also does not fail for other string printing functions like putStrLn.
The equivalent code in C works fine. I've attached both a C and haskell version for comparison.
