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.
