[R-pkg-devel] Stack smashing detected (dynamically loaded Fortran).

<SNIP>

d2f is declared to have dimensions (kstate,npar,npar) in derivf.f, but
is only a real(kind=8) in its caller, getgl.f. Setting the correct
dimensions in getgl.f seems to fix the crash.

Aaaarrrghhhh!  Yes, that must be it. (And likewise with d2u, d2zeta,
...).  I was trying to use derivf to handle settings in which I only
wanted first derivatives as well as ones in which I wanted both first
and second derivatives.  And I buggered it up. As me high school mates
used to tell me, if I had a brain, I'd be sitting on the floor playing
with it!

Thanks Ivan for your diligent, well organised and clever tracking down
of the problem.  I shall retain your email with the illustration of
using "AddressSanitizer" etc., for future reference.

Thanks again.  I owe you, big-time!

cheers,
