#2989: ByteString causes C stack overflow in generated code
--------------------+-------------------------------------------------------
Reporter: Olathe | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.1 | Severity: normal
Keywords: | Testcase:
Os: Windows | Architecture: Unknown/Multiple
--------------------+-------------------------------------------------------
I accidentally left off the apostrophe in the following code.
{{{
cData = L.copy cData'
}}}
That's how I found out that 'fix copy' causes Haskell programs to die.
{{{
import Data.ByteString.Lazy
import Control.Monad.Fix
main = print (fix copy)
}}}
{{{
