Hello, The test program below compiles fine with gcc 4.5.0 but triggers a build error with sparse (git repository last updated on July 11). This seems like a sparse bug to me. Is this a known issue ? #define BUILD_BUG_ON(e) (void)(sizeof(struct { int:-!!(e); })) struct s { char c; int i; } __attribute__((packed)); int main(int argc, char** argv) { BUILD_BUG_ON(sizeof(struct s) != sizeof(char) + sizeof(int)); return 0; } Bart. -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
