#4199: createDirectoryIfMissing fails if directory exists on 32-bit windows
-------------------------+--------------------------------------------------
Reporter: creswick | Owner:
Type: bug | Status: new
Priority: normal | Component: libraries/directory
Version: 6.12.1 | Keywords:
Os: Windows | Testcase:
Architecture: x86 | Failure: Runtime crash
-------------------------+--------------------------------------------------
createDirectoryIfMissing generates an exception when running on 32-bit
windows.
{{{
$ ./dirbug.exe "c:\\cygwin\\home\\hudson\\tmp\\dirBug\\foo"
dirbug.exe: CreateDirectory: invalid argument (Cannot create a file when
that file already exists.)
}}}
I've verified this behavior with 32-bit vista with c and asm backends
using ghc 6.12.1 and 6.10.4.
{{{
import System.Directory ( createDirectoryIfMissing )
--
-- 6.12.1 fails with:
-- $ ghc -fvia-c
-- $ ghc -fasm
--
-- 6.10.4 fails with:
-- $ ghc -fasm
-- $ ghc -fvia-c
main :: IO ()
main = do
createDirectoryIfMissing True "foo"
createDirectoryIfMissing True "foo"
}}}
This does *not* throw an exception on 64-bit vista, and this also does not
throw an exception when running interpreted (either ghci or runhaskell).
