Description: MSVC emits a possible loss of data warning when building 32bit version of _sqlite3.Connection.serialize(), whose data size is should be limited to 0x7fffffff in sqlite-3.38.4.0/sqlite3.c, even on 64bit python (EDIT: Sorry, I missed the pages): SQLITE_PRIVATE void *sqlite3Malloc(u64 n){ void *p; if( n==0 || n>=0x7fffff00 ){ /* A memory allocation of a number of bytes which is near the maximum ** signed integer value might cause an integer overflow inside of the ** xMalloc(). Hence we limit the maximum size to 0x7fffff00, giving ** 255 bytes of overhead. SQLite itself will never use anything near ** this amount. The only way to reach the limit is with sqlite3_malloc() */ p = 0; }else if( sqlite3GlobalConfig.bMemstat ){ ... #92434
