2. problem
   When handling aggregate queries, the BE server may crash. The stack trace shows that the crash occurs in the doris::CRC32Hash::operator() function when calculating the hash value of a StringRef object. This issue is more likely to be triggered when the size of the StringRef is not a multiple of 8 (e.g., 15 bytes).

3. cause analysis
   through GDB debugging, we found:
   3-1. the crash occurs during the hash table resize process, when calculating the hash value of a StringRef
   3-2. he issue is that the size of the StringRef is 15 bytes, and the data pointer is valid
   doris::vectorized::UInt64 word = unaligned_load<doris::vectorized::UInt64>(end - 8);
when the size of the StringRef is 15, the code attempts to read 8 bytes starting from data+7. Although these bytes exist in memory, such unaligned memory access may cause a crash on some architectures

4. GDB

0x5609af33c000: 0xea    0xa1    0xae    0x0d    0x00    0x00    0x00    0x00
0x5609af33c008: 0x03    0x00    0x00    0x00    0x55    0x54    0x41    0x00

the 8 bytes starting from data+7 span across two memory lines, which may cause unaligned access issues

Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

1. What problem was fixed (it's best to include specific error reporting information). How it was fixed.
2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
3. What features were added. Why was this function added?
4. Which code was refactored and why was this part of the code refactored?
5. Which functions were optimized and what is the difference before and after the optimization?
