row_merge_create_fts_sort_index(): Initialize dict_col_t in an unambiguous way. GCC 6 and later appear to be able to optimize away the memset() that is part of mem_heap_zalloc() in the placement new call. Let us avoid using placement new in order to ensure that the objects will actually be initialized. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71388 https://gcc.gnu.org/ml/gcc/2016-02/msg00207.html While the latter reference hints that the optimization is only applicable to non-POD types (and dict_col_t does not define any member functions before 10.2), it is most consistent to use the same initialization across all versions. |
