Versions of OWAMP before 3.0a have problems with some of the optimizations done by the latest versions of GCC. The temporary fix is to add the -fno-strict-aliasing flag to your compile line. This is done by setting the CFLAGS environment variable (BEFORE running ./configure):

export CFLAGS='-g -O2 -fno-strict-aliasing'

Those of you interested in how the aliasing problem usually manifests itself can see details at https://mail.internet2.edu/wws/arc/owamp-users/2006-07/msg00000.html.
