However, this handler catches IO exceptions only! Following the advice from this thread I changed the handler as follows:
Control.Exception.catch
that is a well-known (for gurus :) problem. Haskell98 supports catching of IO exceptions only and corrresponding 'catch' was even included in Prelude. modern Haskell compilers supports catching of any exceptions but to ensure full H98 compatibility, function to catch all exceptions is exposed under different name, namely Control.Exception.catch. so to use "proper" catching you need to work via functions in these module, either qualifying them or hiding 'catch' from Prelude: import Prelude hiding (catch) import Control.Exception if you still don't read "Tackling the awkward squad: monadic input/output, concurrency, exceptions, and foreign-language calls in Haskell" http://research.microsoft.com/Users/simonpj/papers/marktoberdorf/marktoberdo... - i highly recommend you this paper -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
