Hi, i am new in sqlcipher.
I use sqlcipher to encrypt sqlite3 database. I built sqlcipher.dll myself with source code which version is 3.41.2. I met crash several times. Sometimes error module name is ntdll.dll, sometimes error module is sqlcipher.dll. I met an error today. The error module name is ntdll.dll.
I use windbg to locate the root cause. The result is:
I don’t know how to fix it. Could you please help me if you have met this issue. Thanks a lot.
