ghc-6.10.4 segmentation fault in ghci with Text.Regex.Posix

[waterson@…]

After doing a single operation with Text.Regex.Posix, ghci crashes with a segmentation fault. This on Snow Leopard, using ghc-6.10.4. I was unable to reproduce with the Haskell Platform (6.12.1).

Sorry, I misread the steps to reproduce. I'm attaching the crash log.

Port abandoned, #35561.

This ticket is obsolete, since GHC has been updated since.
