VACUUM operation makes memory go up continously for big database(13G) in my computer

[jackinelee]

Expected Behavior

When I do vacuuming operation for a big database about 13G using latest SQLCipher code in git,
I found the memory go up high continuously, but when I use pure SQLite3 3.28.0 to test , it doesn't make memory high , so I don't know where I am wrong to use SQLCipher or some bug in SQLCipher

Actual Behavior

it shoudn't make memory go up high continuously, which seems memory leak issue

Steps to Reproduce

Just do VACCUM operation for a big database , then you will see memory go up high continously
SQLCipher version:
4.2.0
Note: If you are not posting a specific issue for the SQLCipher library, please consider posting your question to the SQLCipher discuss site. Thanks!

@jackinelee - Please provide some information as follows:

1. Is the database you are vacuuming encrypted, or are you observing this behavior on a non-encrypted database when vacuuming with SQLCipher?
2. What version of SQLCipher are you testing with?
3. How are you measuring the memory utilization?
4. What specific platform are you running this test on and how did you build SQLCipher for that platform?
5. How fragmented is the database you are vacuuming (e.g. what do PRAGMA page_count and PRAGMA freelist_count return?
6. Are you able to reproduce this with multiple databases or is it happening only with one specific database?
