The data lists that used to be duplicated are now held in a single common Python module. +19. On CHERI, and thus Arm's Morello prototype, pointers are represented as +hardware capabilities, which consist of both an integer address and additional +metadata, meaning they are twice the size of the platform's size_t type, i.e. +16 bytes on a 64-bit system. The ovector member of heapframe happens to only be +8 byte aligned, and so computing frame_size ended up with a multiple of 8 but +not 16. Whilst the first frame was always suitably aligned, this then +misaligned the frame that follows, resulting in an alignment fault when storing +a pointer to Fecode at the start of match.
