Unfortunately I am away from my developing platform, I'll be back on
Monday. I think increasing the lwork size for the complex routines in
the generalized eigenproblem case may help. I think the minimal lwork
assumptions I have made may need to be relaxed a bit. As i already
explained, I did not understand the code in calc_lwork.f enough to be
able to write an lwork calculator for the eigh routines: doing this
will be the best option, but it may take sometime (and someone else's
work). If you send me the exact failing tests  (so that I can check
which routine is failing) I may try to repair it within Monday
afternoon (European time).
Are you ging to be online or can you give me access on a machine where
the tests are failing?

thank you!

PS: for obvious reasons I would be really happy to see the improved
eigh in scipy 0.7 ;-))
