Situation normal 0 }}} Haskell Exceptions are also language level, they don't throw an actual signal so they shouldn't be triggering the exception handlers. More likely than not, since it happens across compilers, you have an external process interrupting your Haskell program. using the `8.4.1` alpha compile your program with `-debug` and run it with `+RTS --generate-crash-dump` and upload the dump somewhere and link it back. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14669#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
