--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- (In reply to LdB from comment #3) > I am stunned you could not build the code the only requirement is you > include the stdint.h so the uint32_t types are defined. I will fix the typos > are you really saying you can't compile this? > Most compiler developers do not install a complete build environment when testing bugs. As such, they do not have the headers available. This is why our bug reporting rules ask you to post _preprocessed_ source code. You've also failed to give: The options used to configure the compiler when you built it (see the output of gcc -v). The list of options you passed to the compiler when running it. We can only infer -O2 from your comments. > Alignment is not really a concern it's a hardware register to the CPU so > it's a given. Absolutely alignment is the issue here. Packed says that the object can be on any alignment boundary and that materially affects the compiler's behaviour here.
