I am able to repeat the bug using regex 0.93.1 and ghci (version 6.13.20100309). I've filed a trac report. In the meantime, any suggestions on what I might do to work around the problem? Is there a way to upgrade to the most recent HEAD version without going through a complete reinstallation (which takes hours)? Kathleen On Jul 13, 2010, at 4:23 AM, Simon Marlow wrote:
I tried this here with regex 0.93.1 and GHC build yesterday, and couldn't reproduce it on either 32 or 64-bit x86.
Cheers, Simon

Don's right. If it's reproducible please file a Trac ticket.
