In the parser. IN. THE. PARSER. Any hooks/events available to plugins happen significantly later in the pipeline. Thus, SPSLR can not detect offsetofs, be it \_\_builtin\_offsetof or the DIY variants `(((size\_t)&((struct S\*)0)-\>m))`, using current GCC versions. To deal with this reliably, using a custom GCC build is the only way. The required patch is provided in this repo. To use it and install the custom gcc, use these commands:
