This is by design, -fbreak-on-exception breaks on any exception, be it captured or not, even on library code.
Ah, that's what I missed. I would've guessed that it only breaks on uncaught exceptions.
I am not sure how readFile is implemented internally, but it probably reads from the file until an eoferror is thrown and then captures it gracefully.
That's what I expect, too. I went fishing, but didn't find the exact spot where that happens within a few minutes.
There is another debugger flag, -fbreak-on-error, which only breaks on unhandled exceptions. Is this what you want ?
Probably. Now I see the difference in [1]. Thanks! [1] http://www.haskell.org/ghc/docs/latest/html/users_guide/flag-reference.html#... Regards, Sean
