--- Comment #12 from Liam Powell <liam at liampwll dot com> --- I narrowed this down a bit more to 4.2.4 and 4.3.3 since I have binaries for those. The -gnatG output is effectively identical between these versions so the issue is somewhere in the runtime, however I can't see anything relevant in the diff when searching for keywords.
