What I would like to know is if switchtest fails in the same condition
as your non real-time applications, just to see if the situation you
observe is an FPU bug. But for switchtest to start correctly, you need
to increase CONFIG_XENO_OPT_SYS_HEAPSZ.
I significantly increased CONFIG_XENO_OPT_SYS_HEAPSZ and switchtest
seems to me runs fine:

My problem with non-RT application happens only if RT application
(running in the same time) uses native skin. Perl and Eclipse
application fails when switchbench is running, but not problems during
switchtest.
