[Discuss-gnuradio] Volk "make test" Failure on OSX on Next Branch, sometimes

[Michael Dickens]

OSX 10.8 latest, Xcode latest, GNU Radio next branch latest, using llvm-gcc-4.2 
for the compiler.  From the build directory, if I execute "ctest -V -R volk", 
it succeeds about 3/4 of the time; it fails about 1/4 of the time with the 
attached text (always the same text).  Hopefully someone who knows Volk can 
make sense of it; I'm happy to try out fixes. - MLD
