    Fix heap corruption during stable name allocation · 22cd729a
    Ömer Sinan Ağacan authored
    See #15906 for the problem. To fix we simply call `allocate()` instead of
    `ALLOC_PRIM()`. `allocate()` does not trigger GC when the nursery is full,
    instead it extends it.
    
    Test Plan:
    This validates. memo001 now passes with `-debug` compile parameter. I'll add
    another test that runs memo001 with `-debug` once I figure out how to use
    stdout files for multiple tests.
