[ADOL-C] [SOLVED] Mismatched free() / delete / delete [] in documentation examples..

[Antonello Lobianco]

SOLVED :-)

I used the slightly modified generate_tape() and deallocation part of
finalize_solution() of the bocop package (http://www.bocop.org, file
bocop-1.0.3-beta/new_nlp/BOCOP_Problem.cpp) .. no more valgrind errors and
problem that solve indipendently from HPOFF and the number of times it is
run...

So for anyone trying to use Ipopt/Adol-C/ColPack together they should use
that version as the one in the adol-c documentation has the reported issues.

Thanks everyone :-)
