It appears the problem is that in sparc, you can't just say
*(datatype*)data. Depending on datatype, 'data' has to be aligned at a
certain number of bytes from the original block (4 for int, 8 for
int64):

char* src = something();
int* tmp = (int*)(src + 1); // If 1 is replaced by 4, no bus error.
*src = 1; // Bus error here.
int a = *src; // This yields bus error too

So, at least lo_message_add_data (plus all its users),
lo_arg_pp_internal and lo_arg_host_endian need to change to support
sparc.
