Summary: Compiler stack underflow bug with IF based switch statement
Original Submission: The stack tracking in the compiler generates a -1 stack
state which is responsible for the maxStack being one less
than the actual value. The behavior is observed only when
a function inside the switch-case uses >2 args . The
verifier throws a stack underflow bug. The problem was
traced to cg_stmt.tc:1894
The verifier throws a stack overflow error on executing
the compiled binaries.
