SUMMARY: MemorySanitizer: use-of-uninitialized-value /home/jenkins/src/storage/spider/spd_malloc.cc:249:14 in spider_bulk_alloc_mem(st_spider_transaction*, unsigned int, char const*, char const*, unsigned long, unsigned long, ...)

  ORIGIN: invalid (0). Might be a bug in MemorySanitizer origin tracking.

    This could still be a bug in your code, too!

Note: The last lines in the MSAN output above say it may be a bug in MSAN origin tracking, but that's not certain. If you come to the conclusion that it's a MSAN failure, please feel free to close as not-a-bug, but that will likely mean that Spider will remain disabled in CI MSAN tests.
