QEMU's floating point support for ARM is good and known to work.
If QEMU exits with a coredump then that is either:
 * your test binary is dumping core due to a bug in your test
   (assuming you're using linux-user mode)
 * a bug in QEMU (unlikely but not impossible)

If you can provide a reproducible test case we can have a look at it.
