I haven't reproduced this problem, and we still don't have the entire
copy of *some* affected elf file. However, looking at the attachment
and the loc2c code, it seem the following combination is not being
handled by loc2c:
[ e93f3] 0xc0189445 <proc_reg_llseek>..0xc0189455 <proc_reg_llseek+0x10> [
0] reg2
[ 1] piece 4
[ 3] reg1
[ 4] piece 4
To wit, the reg1 piece.
