This error is from inside Gnu Radio, involving the wavefile sink. That's
not a USRP/UHD problem and discussing on the
discuss-gnuradio mailing list would be better.
However, this class of error usually means you have libraries that are
inconsistent on your system, likely from multiple
incompatible compile/build attempts.
This *might* be fixed with a simple:
sudo ldconfig
But more guidance would be available from the discuss-gnuradio mailing list.
