[yt-dev] cython debugging?

Hi all,
I'm trying to extract some data for a surface, but am getting a segfault in
the `YTSurfaceBase.get_data` method - probably the same thing as this [1]
yt issue. I've tracked it down to the `FillTriangleValues` call in
`march_cubes_grid` with a combination of pdb and gdb. I can't figure out
what is wrong, however, because all the variable values are optimized out.
So my question: anyone know how to re-run setup.py and turn on debugging
flags for cython code?
I've found information about cygdb, which would probably be easier than
pdb+gdb. Their documentation says to rebuild with the --pyrex-gdb flag to
setup.py, but that doesn't seem to be recognized by setuptools. Other
webpages say to set the "-g" or "--cython-gdb" flags, but those also do not
work.
