The test case was setting aria_sort_buffer_size to MAX_ULONGLONG-1 which was not handled gracefully by my_malloc() or safemalloc(). Fixed by ensuring that the malloc functions returns 0 if the size is too big. I also added some protection to Aria repair: - Limit sort_buffer_size to 16G (after that a bigger sort buffer will not help that much anyway) - Limit sort_buffer_size also according to sort file size. This will help by not allocating less memory if someone sets the buffer size too high.
