Hi Heba, There are three possibilities: 1) The program requires correct FP exception behavior to work. This usually isn't the case and I don't think we handle arithmatic faults in SE mode correctly for any ISA. 2) There is a bug with our Alpha support that make making you hit his issue 3) There is a bug with gcc that generated the the binary. You should be able to specific -mcpu=21264.
If (1) is the problem then you'll need to run with Linux on some ISA. You can see what happens by compiling and running the app for a different ISA. The FP support for ARM is very solid so I would start there, but be careful about command line again. Depending on the exact compiler you're using you generally need to specify VFPv3 support and/or neon.
