Instead of the expected WS FULL, I got the following error when trying to sum a large array:

      +/ ,9 (⌊n÷9) ⍴ ⍳n←20000000000
Value_P::Value_P(ShapeItem len, const char * loc) failed at Value_P.icc:107 (caller: Bif_F12_INDEX_OF.cc:44)
 what: std::bad_alloc
 initial sbrk(): 0xeef000
 current sbrk(): 0xeef000
 alloc_size:     0x6fc23ac000 (480000000000)
 used memory:    0x14548 (83272)
WS FULL+
      +/,9(⌊n÷9)⍴⍳n←20000000000
