I'll have a go at creating a minimal example if I get time.

The general case is:

  - package name 'foo'
  - pyrex module 'foo.fred', as foo.fred.pyx and foo.fred.pxd
  - pyrex module 'foo.sub.sub1', which cimports from fred, as
    files foo.sub.sub1.pyx and foo.sub.sub1.pxd
  - ditto for 3 or 4 other modules 'foo.sub.subx'
  - build this
  - from a pure python module, do:

        import foo.sub.sub1
        import foo.sub.sub2
        import foo.sub.sub3
        import foo.sub.sub4

This likely will crash, or do other nasty things.

If you can't reproduce this, then I'll take the source tree where I'm
seeing this, and keep pruning stuff out as far as I can while keeping
the problem observable.

Cheers
