Application runs well on 4m but not on 4u...

Hi All,

Exactly same OS (2.5.1) same pacthes but an application works well on 4m machine (Sparc20) but not on 4u machine (Ultra 1). Processor families are different Ultra's more recent one, I know that. Maybe some cpu specific compiler directives were used while compiling the application. Any idea welcomes..

Thanks
