If this is system QEMU emulation, that strongly suggests a QEMU bug, not a 
glibc bug - meaning you should find where the execution diverges between 
QEMU and hardware to identify the mis-emulated instruction.

(For QEMU usermode emulation, different address space layout compared to 
running natively under the Linux kernel could be an issue.)
