Hi All I have compiled a binary using gcc 4.2.3 on a SPARC/Solaris 10 machine. Every time I run this program, it dumps core and upon checking the core, the error line is : t@1 (l@1) program terminated by signal BUS (invalid address alignment) Any idea what this is. I checked the binary for any 64-bit libraries that got linked. I could not find one. I would very much appreciate your help. With Regards Vardhan
