Description

At Line 234, the condition of the BranchInst is dynamically casted into ICmpInst. However, the condition is not always ICmpInst. For example, it could be a CastInst which casts an i32 into an i1. In this case, the variable cmpInst would be null and a NPD will happen at line 236.

At Line 1092, the situation is similar.

Proposed Fix

guard this dyn_cast with a if
