  *** rnfinit: bug in GP (Bus Error), please report

This also occurs with version 2.3.0, both on the (Intel) MacBook and the PowerPC PowerMac. I have tried this on a couple of Linux/ x86 systems without seeing the bus error, so it is in some way related to the Mac. I won't be able to look at this until late this week, but if anyone has a thought, please pass it my way.

FWIW, both of the 2.3 versions were built as part of SAGE. I have not yet built the release version of GP on its own.

I have built 2.3.0 on a G5 PowerMac and a MacBook Pro. Neither of them exhibits the bug.

Are you using a GMP kernel?  Which version of GMP?
