OK, have tracked it down thanks to help from the list. > Christophe Seguinot writes:

It appears in 3.8 that OOT shared library .so symlink does not update to the newest installed version, but leaves it pointing to the older version. My recollection is that this is different behavior than gnuradio 3.7.x I went in and manually deleted all the shared libraries for my OOT in/usr/local/lib/x86_64-linux-gnu and then re-did sudo make install. That created the correct symlink to the new version, and the memory error problem seems to be gone. -- Tom, N5EG
