I've tracked down this problem, and the good news is that it is nothing to be
concerned about.
It turns out to be a bug in g++ 4.7.x that affects the pml.cpp test program,
but not Meep itself. I confirmed the bug with the gcc developers and they
will hopefully fix it in the next gcc release:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54498
In the meantime, you can ignore the failure of the PML test. If you want to
verify that the PML test passes, a workaround is to compile the PML test
without optimization:
cd tests
rm -f pml.*o
make CXXFLAGS=" " pml
The next release of Meep will contain a workaround to avoid triggering the gcc
bug in the test program.
