I doubt this can be seen in a cross: running the compilation under truss reveals the SIGBUS as 2834: Incurred fault #5, FLTACCESS %pc = 0x00723E58 2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954 2834: Received signal #10, SIGBUS [caught] 2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954 i.e. an unaligned access. While SPARC is a strict-alignment target, x86 cares little if any about alignment at all. > You could try /var/gcc/reghunt/sigbus-range/288807/./gcc/xgcc -save-temps > [blah blah], and attach the libgcc2.i file that gets generated.
