The plot thickens. I was eventually able to = reproduce the same buggy behavior without the HEAD commit, = *sigh*

It appears that = the bug happens randomly between consecutive module loads/unloads. It = also appears that once the module is loaded in a =E2=80=9Cworking = state=E2=80=9D it keeps working fine.

I=E2=80=99m wondering if this could be an =E2=80=9C= use of uninitialized data=E2=80=9D type of = bug.

If that makes any = difference, I=E2=80=99m using tc-adv 2f0d76d8 (i.e. current master = HEAD)
