Hi all,
I tried to modify one of the ThyraModelEvaluator example to solve one
of my problems, and when I run the code I get the following error
(from gdb)
********************************
*** Start of rSQP Iterations ***

Oops! Not the solution. Some error has occured!
Number of function evaluations:
-------------------------------
f(x) : 0
c(x) : 0
Gf(x) : 0
Gc(x) : 0
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
AbstractLinAlgPack::VectorSpaceThyra::is_in_core (this=0x10933b50)
at ../../../../../packages/moocho/thyra/src/AbstractLinAlgPack/
AbstractLinAlgPack_VectorSpaceThyra.cpp:100
I tried to spot the exact function that jumps, and I found out that
it is caused by the call in NLPInterfacePack_NLPThyraModelEvaluatorBase
preprocessBaseInOutArgs( ... )
which calls
model_outArgs.setDgDx( ... ).
I only modified the size of the problem and the fact that I don't
support derivatives other than W = DfDx. I call the example with
test --moocho-thyra-params-file="thyra_fd.xml"
where thyra_fd.xml switches on the FD calculation of DgDx, DfDp and
DgDp. A part from this, everything else is exactly the same as the
example, however the program never gets to the evalModel method...
Any ideas on what could be going wrong?
Thanks in advance.
Luca.
