Hi,

   I am working with the latest xenomai-head tree (we need analogy for  
our NI board ...). Under Xenomai 2.4.8 our code did not have any mode  
switches. Using the xenomai-head, we get a lot of mode switches. Using  
he backtrace_symbols_fd, we get print-outs like:


xsimulation[0x808553b]
[0xffffe400]
/usr/xenomai/lib/librtdk.so.0(assert_nrt+0x85)[0xb7fa2ea5]
/usr/xenomai/lib/librtdk.so.0(__wrap_clock_gettime+0x17)[0xb7fa2ef7]
xsimulation[0x807cd16]
xsimulation[0x807d7fb]
/usr/xenomai/lib/libnative.so.3[0xb7fab689]
/lib/tls/i686/cmov/libpthread.so.0[0xb7f824ff]
/lib/tls/i686/cmov/libc.so.6(clone+0x5e)[0xb7e8f49e]

Which indicates that the wrapper for clock_gettime causes this  
trouble, which is also confirmed by commenting clock_gettime out, and  
the  mode switches disappear.

  Maybe something that needs fixing?

Best wishes,

-Stefan
