hipe segmentation fault

In my case the host has 2 CPUs (seen as 4 in hyper-threaded mode), which 
support 64-bit architecture, yet 32-bit Linux RedHat ES 4.0 is installed.

I did remove, plain vanilla compile and reinstall Erlang, and still get 
the same core dump.  I am second guessing my prior statement about this 
test running successfully on another host with the same hardware.  Right 
now I don't have access to that machine, but will get a chance to verify 
that later on this week.

$ cat /proc/cpuinfo | egrep "processor|model\ name"
processor       : 0
model name      : Intel(R) Xeon(TM) CPU 3.60GHz
processor       : 1
model name      : Intel(R) Xeon(TM) CPU 3.60GHz
processor       : 2
model name      : Intel(R) Xeon(TM) CPU 3.60GHz
processor       : 3
model name      : Intel(R) Xeon(TM) CPU 3.60GHz

The box has 4G RAM.
