I am actually running the released 1.1. I can send you my code, if you want, and you could try running it off a single node with -np 4 or 5 (oversubscribing) and see if you get a BUS_ADRALN error off one node. The only restriction to compiling the code is that X libs be available (display is not required for the execution though it's more fun :P)

As you will notice in "my thread", I am running into problems on Sparc SPM systems where the CPU borad's RTC are in a doubtfull state. Are-you running 1.1 on SMP machines. If so, on how many procs and what hardware/OS version is this running off?
