     7  // Issue 80097: ICE "invalid heap allocated var without Heapaddr"
     8  // when a heap-escaping variable is declared in unreachable code.
     9  // Escape analysis marks the variable as heap-allocated, but because
    10  // the declaration is dead, SSA generation never assigns it a heap
    11  // address. DWARF generation must tolerate this state.
