[SciPy-Dev] Recently discovered bug in lots of code mixing C and Fortran

[Nathaniel Smith]

Apparently there is a common situation where C code calling into
Fortran violates the Fortran ABI, and has been accidentally getting
away with it for years, but in the near future it will start causing
mysterious crashes:

Both CBLAS and LAPACKE are specifically called out as including broken
code, so I guess this is pretty widespread. I don't know if it affects
scipy directly, but I'm guessing at least some people reading this
list have some code that's affected, so... heads-up.
