We are hitting this with our application, VisIt, using software rendering with
OSMesa 7.8.2.

 fb->Attachment[bufferName].Renderbuffer == ((void *)0)' failed.

This is with our current trunk.  Mesa is built using the autoconf build system:

    ./configure \
      CC="${C_COMPILER}" \
      CXX="${CXX_COMPILER}" \
      CFLAGS="${CFLAGS} -DUSE_MGL_NAMESPACE"     \
      CXXFLAGS="${CXXFLAGS} -DUSE_MGL_NAMESPACE" \
      --prefix=${PF}                    \
      --without-demos                   \
      --with-driver=osmesa              \
      --disable-gallium                 \
      --with-max-width=16384            \
      --with-max-height=16384           \
      --disable-glw                     \
      --disable-glu                     \
      --disable-egl

AFAIK, we don't actually use glRenderbuffer* in our application, so I guess
there is an implicit buffer for the implicit display?

More information as I know it...
