#1998: Stricter enumFrom instance for Integer, to match Int
-------------------------------+--------------------------------------------
Reporter: dons | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.8.3
Component: libraries/base | Version: 6.8.2
Severity: normal | Keywords: Integer, strictness
Difficulty: Easy (1 hr) | Testcase:
Architecture: Multiple | Os: Multiple
-------------------------------+--------------------------------------------
Stack overflow for enumFrom :: Integer (but not enumFromTo nor for Int).
{{{
main = print (head (drop 1000000 [1 .. ]))
Stack space overflow: current size 8388608 bytes.
Use `+RTS -Ksize' to increase it.
}}}
Due to lazy accumulator for Integer enumFrom.
Patch and library ticket here:
http://hackage.haskell.org/trac/ghc/ticket/1997
It looks like it could be a GHC bug report instead of a library proposal
(similar to the buildr/fold failures), so reporting it as a GHC issue.
