Hello,
I've written a simple sequencer[0] using gtk2hs and control-timeout[1]. In GHCi it works fine, but when I compile it, the timeouts generated by control-timeout are not executed. Actually, when I use the keyboard a lot, at some time they got executed. I thought it could be that these two packages are incompatible, but the I wondered why they work in GHCi.
Any ideas?
Just a guess, but this might be a problem with control-timeout's use of the unsafePerformIO global variables hack. It's missing the standard NOINLINE annotations which prevent multiple copies of the global variable from being created. See the haddock docs for System.IO.Unsafe.unsafePerformIO for more information. -Judah
