This one is strength reduced for 3.4 but not for 4.0. typedef struct { union { unsigned int Init[9]; unsigned char Link[37]; } u; } BitStreamLinkStruct; void f2(BitStreamLinkStruct *); void f1 () { int ixBlock; BitStreamLinkStruct bitStreamLink; for(ixBlock=0; ixBlock<=7; ixBlock++){ bitStreamLink.u.Init[ixBlock] = 0x1e1e1e1e; } f2(&bitStreamLink); } -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18768
