I belive this is a bug in sine.so LADSPA plugin. See e.g. this
older thread:
http://www.eca.cx/ecasound-list/2009/02/0003.html

This error message is emitted by newer versions of glibc (so the problem
has been there all the time, but older glibc versions didn't warn about
it).

The mail linked above has some suggestions how to get rid of the error.
