#4119: File buffering isn't flushed at exit
------------------------------------------+---------------------------------
Reporter: EyalLotem | Owner:
Type: bug | Status: closed
Priority: normal | Milestone:
Component: libraries/base | Version: 6.12.1
Resolution: invalid | Keywords: file buffers
Difficulty: | Os: Linux
Testcase: | Architecture: x86_64 (amd64)
Failure: Incorrect result at runtime |
------------------------------------------+---------------------------------
Changes (by igloo):
* status: new => closed
* resolution: => invalid
Comment:
This is an example of how finalizers aren't guaranteed to be run. If you
use `withFile` then the handle will be closed and the data written, even
if there is an exception:
{{{
import System.IO
main = withFile "test.txt" WriteMode $ \h ->
hPutStrLn h "Hello world"
}}}
