Comment (by Sebastian Huber):

 We were able to reproduce the issue. It is a problem in the FPU context
 save/restore during interrupt processing. Under certain conditions, the
 FPU context is restored from an uninitialized frame which could enable the
 flush-to-zero configuration. I am currently quite busy. I will add it to
 my TODO list, but it could be September/October.
