The problem returned, but I fixed it more permanently in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/0eea9ccbae22).

Nice, the problem seems to have gone away by itself.  Closing report.

I can't confirm this bug with current dev (today clone). I obtain the same function calls list (except the recursive one) but:
 - each one is called one time less (e.g. sind is called only once as expected)
 - not exactly the same order.

The profile command is producing an erroneous first line which dominates all the other function calls.  The function has no name and is marked as R(ecursive).  This is a regression from 3.6.4 where the profiler worked.

Sample code:


octave:5> profile clear
octave:6> profile on
octave:7> y = sind (30);
octave:8> profile off
octave:9> profshow (profile ('info'))
