[Haskell-beginners] Re: timer_create: Invalid argument

[Maurí­cio]

It seems it's a know question:

http://thread.gmane.org/gmane.comp.lang.haskell.cafe/49337

One of the problems discussed in that thread is the timer_create
issue, but it seems upgrading is the sugested solution.

Did Daniel mean to open a bug report on Red Hat or GHC? If you
ever want to report a bug on GHC:

http://haskell.org/ghc

The ReportABug link do have nice instructions. But maybe
this is worth discussing in haskell-cafe first, so I posted
a message there:

http://thread.gmane.org/gmane.comp.lang.haskell.cafe/59643

Best,
Maurício
