Re: segfault/massive memory use when using Data.Bits.shiftL

ganesh:

Hi,

The following either eats memory until killed or segfaults (I can't pin down a reason for the difference). Tested with GHC 6.2.2 and 6.4.20050212, with various different libgmp3s under various Redhat and Debian platforms, and WinXP.

Have you tried gmp-4? That's seems to be more stable. -- Don
