OK.
Is there some way to recognise what the function is?
The problem is with ESC/Haskell. I have managed to get the code
integrated into the 6.11
Hi
I believe the following program should always print 100:
import Data.IORef
import Control.Concurrent
main = do
sem - newQSem (-99)
r - newIORef 0
let incRef = atomicModifyIORef r (\a - (a+1,a))
sequence_ $ replicate 100 $ forkIO $ incRef signalQSem sem
waitQSem sem
v
The code assumes newQsem is never given a negative argument without ever
documenting this fact.
http://www.haskell.org/ghc/docs/latest/html/libraries/base/src/Control-Concurrent-QSem.html#waitQSem
change not only
putMVar sem (0, blocked++[block])
to
putMVar sem (avail,
Nowhere. It's a name generated by GHC itself during compilation.

Where is a function with a name like the following defined in the ghc source
code?
.Classes._ ( tpl_B6 )
I've tried searching for such names - all I can find is a comment
referring to tpl_B2.

this is not currently true. They should all be using the modifyMVar_
idiom — currently an exception such as killThread between the take and put
will leave the semaphore perpetually empty

why has PatternSignatures

show me the alleged type variable in this code:
