Re: [SOSlib-devel] sensitivies and compilers...

[Rainer M. <ra...@tb...>]

Hi Eryk,

No, we don't know of any such differences currently. Could you send the 
model or the code?

Have you updated SOSlib, after the sensitivity bug that you had reported 
was fixed? This bug was fixed in 2006-10-13 02:49 as documented at 
sourceforge.

We did a wrong initialization of CVODES sensitivities in version 1.6.0, 
and it worked for normal use but not for iterative use of the same 
solver structure.
However, also for the first run, the correct initialization (to 0) 
depended on the compiler. Some compilers might do this wrongly. So if
you use SOSlib code from before the bugfix, the described bug and 
differences with compilers is easily possible.
