Edit: This has been temporarily fixed, at the cost of ground variables taking up 3x the size.

The Bug

When using external libraries, the args.values[0].data.___Val returns an incorrect value. This makes external libraries completely unusable.

Evidence: Create a custom function, and include printf("%lo\n", args.values[0].data.intVal) at the beginning. This will print a different number to the integer argument that was parsed.

The Cause

This bug goes away when removing the struct GroundStruct* customType; line from within typedef struct GroundValue { ... } GroundValue; definition. I would assume this is due to the new field not being initialised properly in some important function.
