Error occurs when attempting to log anything in SDL application
: hPutChar: invalid argument (Bad file descriptor)
I made test application in EPashkin/hslogger_SDL_test bad branch
Problem can be fixed on application side if call removeAllHandlers before any log action (ex. in start setupLogger).
Source of problem is very strange value of stderr. Don't found way detect it, stderr still opened and writable. Simply hPutChar stderr 'g' will also fail.
P.S. Failing handler IMHO created in System.Log.Logger.logTree.
P.P.S. When application started from console (cabal run) it works fine even on WARNING,
but hPutChar stderr 'g' still failing. (Sorry, was wrong. Error still showing.)
