Seg Fault using DynamicList

Howdy Foamers:

I have a very simple OF application using OF 7.

Code:

#include "fvCFD.H"

#include "uniformDimensionedFields.H"

#include "turbulentFluidThermoModel.H"

#include "rhoReactionThermo.H"

#include "ReactionModel.H"

#include "multivariateScheme.H"

#include "pimpleControl.H"

#include "pressureControl.H"

#include "fvOptions.H"

#include "localEulerDdtScheme.H"

#include "fvcSmooth.H"



DynamicList<Foam::word> wordDynList(0);



int main ( int argc, char *argv[] )  {

    wordDynList.append ( "one" );

    wordDynList.append ( "two" );

    Info << wordDynList << endl;

}

The code compiled but at the end of execution it gave me a seg fault:

Code:

2

(

one

two

)



Segmentation fault

Looking at test suite (Test-DynamicList.C) I could not do anything obvious that would cause the code to crash, nor did I see any any dynamic list being explicitly deallocated (not that it solved the problem). What else did I miss?

Thanks in advance, Gerry.

It looks like the culprit is in the .append() function. I don't know why, though.

Okay, it turns out I needed to deallocate the DynamicList afterall ...

Code:

#include "fvCFD.H"

#include "uniformDimensionedFields.H"

#include "turbulentFluidThermoModel.H"

#include "rhoReactionThermo.H"

#include "ReactionModel.H"

#include "multivariateScheme.H"

#include "pimpleControl.H"

#include "pressureControl.H"

#include "fvOptions.H"

#include "localEulerDdtScheme.H"

#include "fvcSmooth.H"



DynamicList<Foam::word> wordDynList(0);



int main ( int argc, char *argv[] )  {

    wordDynList.append ( "one" );

    wordDynList.append ( "two" );

    Info << wordDynList << endl;

    wordDynList.clearStorage();

}

Note that calling DynamicList::clear() is not enough, DynamicList::clearStorage() resets the list size to zero and free its current contents.

Gerry.
