more test result:
1) the first call the function
dest->Blit( dest, colorkeyed, NULL,
(SW!=SX) ? myrand() % (SW-SX) : 0,
(SY-SH) ? myrand() % (SH-SY) : 0 );
is passed
the second times, call the function dest->Blit( dest, colorkeyed, NULL,
(SW!=SX) ? myrand() % (SW-SX) : 0,
(SY-SH) ? myrand() % (SH-SY) : 0 ); caused a SIGBUS
2) I notice the signal is raised from function static void Bop_rgb16_Kto_Aop(
GenefxState *gfxs )
if I commented out *D = dpixel; it works , below is the codes snap, I guess
may be there some memory problem in __u32 *S = gfxs->Bop[0];
if (dpixel != DSkey) {
if ((dpixel & 0xFFFF0000) != (DSkey & 0xFFFF0000)) {
if ((dpixel & 0x0000FFFF) != (DSkey & 0x0000FFFF)) {
// *D = dpixel;
}
else {
#ifdef WORDS_BIGENDIAN
tmp[0] = (__u16)(dpixel >> 16);ss
#else
tmp[1] = (__u16)(dpixel >> 16);
#endif
}
