Segfault when using -xc to smoke out a <<loop>>
The following program illustrates the problem:
module Main where
data T k = T | S k deriving Show
test :: T k
test = test
main :: IO ()
main = putStrLn $ show (test :: T Int)
When compiled with
ghc --make Main.hs
and run, the program outputs "<<loop>>". Which is fine.
However, when compiled with
ghc --make Main.hs -prof -auto-all
and run with
./a.out +RTS -xc -RTS
the result is a segmentation fault. There is no stack
trace.
The test was done on Gentoo Linux, the CPU is Athlon XP.
