simplejack: schedule: re-entered unsafely.
Perhaps a 'foreign import unsafe' should be 'safe'?
Am I misusing something? Or is this a compiler bug? Google indicated
that the last time someone had this problem it was a compiler bug...
Here is the test program. It requires jack to be running
(http://jackit.sf.net) and I built it with:
ghc --make -fglasgow-exts SimpleJack.hs -o simplejack -ljack
Are jack callbacks invoked on a second thread? (looks like they are).
If so, you need to use the threaded RTS, activated by passing -
threaded to ghc.
ghc --make -fglasgow-exts SimpleJack.hs -o simplejack -ljack -threaded
Cheers,
Wolfgang
