crouched_rifle_firing_animation_group1 (chr.c) has one entry and no
terminator; on the N64, .data is in source order, so
crouched_rifle_firing_animation_groupA follows it and the single
initResolveAnimGroupTable pass over group1 also resolves groupA (len 2).
GCC places groupA below group1, so groupA[0] kept the raw anim offset
0xB84 (PTR_ANIM_fire_kneel_left_leg). playerTick (bondview2.c:11021) passes
it to modelSetAnimation for a player's crouched rifle fire
(firing_animation_groups[1][5]) -> SIGSEGV in modelConstrainOrWrapAnimFrame
(fault 0xb88). Crouching rifle guards also saw len 1 instead of 2.
#ifdef PORT: one array {right_leg, left_leg, terminator} (the N64 layout),
groupA = &group1[1] (chr.h). ABI/layout exception, porting-notes D5 class
(D164 precedent). Verified: 4-seat repro (M16, Complex, frame 5030) runs
5 min x3 SH-identical, no crash; gdb scan of all firing_animation_groups
entries: 1 bad pointer before, 0 after; P1 corpus (1324 recordings) verdicts
identical; solo/couch frames byte-identical; netplay 2P/4P identical.
