Yep. It's a rare case as you say. I could find such codes in very huge
functions only.

It's just a guess but the compiler can avoid this relocation by generating
braf instruction instead of jmp in PIC case, though the current code itself
doesn't seem incorrect.

ok. I'll send yout them ASAP.
Thanks you for replying.
