--- Comment #4 from Roger Sayle <roger at nextmovesoftware dot com> --- This is either (i) related to PR 103773, where GNAT is somehow setting optimize_size to a value greater than 1 (i.e. -Oz) and getting hit by the known memory corruption or (ii) somehow related to the highpart multiplication changes (which on double checking look sound) or (iii) caused by someone elses changes. If we could identify which patch to revert to resolve the issue, or even which hunk, that would help. I'm attempting various gnat bootstraps myself. Sorry for the inconvenience.
