As of mentioned versions MCS returns cryptic messages if expection is raised in BPP::execute().
Here is the example how MCS fails trying to call Row::getIntValue() from a non-int column.

There are no means to raise a warning from PrimProc. It is important for wide-decimals when MCS has to reduce the value down MAX_INT executing operation. Right now it does it w/o notifying the user.
