Segfault when using -xc to smoke out a <<loop>>
|Reported by:||blamario||Owned by:||simonmar|

|Test Case:||Blocked By:|
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.
