Boundary condition with mpirun

I just implemented Lund's recycled boundary condition (thank you Perry Johnson ) in OpenFOAM, and it seems to work just fine on a single processor.
However, when I run the simulation on several processors, I get a pretty uggly error (sigSegv, sigFpe, etc...). Is there anything I should be doing to parallelize my code?
Basically, the algorithms starts with
void Foam::scaledMappedVelocityFixedValueFvPatchField:: updateCoeffs()
// Since we're inside initEvaluate/evaluate there might be processor
// comms underway. Change the tag we use.
int oldTag = UPstream::msgType();
UPstream::msgType() = oldTag+1;
// Get the mappedPatchBase
const mappedPatchBase& mpp = refCast<const mappedPatchBase>
const fvMesh& nbrMesh = refCast<const fvMesh>(mpp.sampleMesh());
const word& fieldName = dimensionedInternalField().name();
const volVectorField& nbrField =
after that, I extract a plane from the domain, scale it, and eventually return the inlet as follows:
// return the velocity values to inlet condition
// Restore tag
UPstream::msgType() = oldTag;
If someone had an idea, it would be really great! I don't really feel like running my LES on a single processor.
