Could it be that there's actually enough heap but we're mis-interpreting the build output?

@rgrover There is enough heap, the problem is that from that table it is very difficult to identify which is the actual heap section because of the symbols that have been used. So the reason why the message is printed is because the script checked:

ARM_LIB_HEAP            0

[rgrover]

is the actual heap-size a MAX() of ARM_LIB_HEAP lines?
