Declaring the struct __attribute__((packed)) yields the error "cannot bind packed field 'data.Data::id' to 'long long unsigned int&'" which fits your explanation. However, declaring it __attribute__((aligned(1))) compiles (but still fails at runtime). Shouldn't the compiler complain about misaligned references at the call site? Christian
