gunUpdateAndFire's KF7 branch (`mdlhdr->Skeleton == &skeleton_gun_kf7`) does `((f32*)stackpad2)[-8] = ...` then reads it back into matrix_scalar_multiply -- a decomp register-allocation stackpad: a scratch f32 the N64 compiler placed 32 bytes below the `u8 stackpad2[4]` local. GCC's x86-64 stack layout is different, so the negative index scribbles into an unrelated stack slot (return-address / saved-reg area) -> 0xc000001d illegal-instruction the moment you fire a KF7. Found via scripted-input (walk+fire) testing: 12 campaign levels survived a firefight script, Caverns (-level_39) crashed reproducibly on a settled machine at gunfire.c:817. addr2line -> gunUpdateAndFire. The KF7 is a common campaign weapon (Facility/Surface/Caverns guards) so this would hit the user early. Fix: real `f32 kf7_flashscale` local under #ifdef PORT; N64 stackpad expression kept under #else. Caverns now survives repeated fire to frame 1500+; -level_09 unregressed. PORT-LEARNINGS §A (stackpad hazard).
