Hi All.
--------

I wrote an application on Ultra-10 machine and when I run it on Ultra5
machine , the application
is crashing on bus error ( Invalid address alignment ) although on
Ultra10 it's running good !!!.

My questions:
- Why my application crashing on bus error on the Ultra5 platform and
not on the ultra10 platform ?
- Is the bus of Ultra5 different than the Ultra10 bus ?
- Is there's a way to fix bus problems so my application would run on
both machines ?

A N Y help will be appreciate ,
please replay to:

The problem you have here has nothing to do with the hardware inside the
SUNs. The problem is to do with your program running around memory and
not aligning a pointer/struct correctly. Could have shown up before, but
may be different SOlaris versions or patch level. Using dbx etc you
should be able to trace what's going with you code and fix it.
