Detailed Description

SymbolicRegion - A special, "non-concrete" region.

Unlike other region classes, SymbolicRegion represents a region that serves as an alias for either a real region, a NULL pointer, etc. It essentially is used to map the concept of symbolic values into the domain of regions. Symbolic regions do not need to be typed.
