I bumped into a segmentation fault in the regex library today and thought I'd warn others in case similar behavior is observed:
Prelude> :m Text.Regex Prelude Text.Regex> map read (splitRegex (mkRegex "\\|") "0|1|2|4") :: [Int] Loading pack:age syb ... linking ... done. Loading package array-0.2.0.0 ... linking ... done.

I am on Ubuntu 10.04 with GHC 6.12.3, regex-base-0.93.2, regex-posix-0.94.4 and regex-compat-0.93.1, and I do not have this problem. See below. Did you try it again? That kind of bug might just be GHCi. If it persists, maybe upgrading should fix the issue. chris@cn-done:~$ ghci GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.
