Missing libsqlite3.a and libsqlite3.a.dylib on Mac Build

BySQLite.work Team

Missing Static and Dynamic Libraries After Configuration When building SQLite from source on a Mac, users may encounter a situation where the expected static library (libsqlite3.a) and dynamic library (libsqlite3.a.dylib) are not generated after running the make command. Instead, only a libsqlite3.la file is produced. This issue typically arises when the build process is configured…

Clang-11.0.0 Miscompilation Issue in SQLite 3.32.1

Clang-11.0.0 Miscompilation Issue in SQLite 3.32.1

BySQLite.work Team

Miscompilation of SQLite 3.32.1 by Clang-11.0.0 The core issue revolves around the miscompilation of SQLite version 3.32.1 when using the Clang-11.0.0 compiler. This miscompilation manifests in the utf.c source file, specifically in lines 345-347, where the compiler incorrectly assumes that the sqlite3VdbeMemRelease() function does not alter the value of pMem->flags. This assumption leads to incorrect…
