Switching from SQLITE 3.36.0 to 3.37.0 on UNIX with TSAN produces race errors. — it appears each connection is locking its own mutex when accessing COMMON data structures (shared between threads). - From the TSAN report, the issue appears to be: Read of size 4 at 0x55c2f79772f8 by thread T4 (mutexes: write M509514):#0 sqlite3VdbeExec /home/lewis/Sandbox/Stroika-Build-Dir-Ubuntu1804_x86_64/IntermediateFiles/g++-debug-sanitize_thread/ThirdPartyComponents/sqlite/sqlite3.c:88607 (Test36+0x492c1b1) withPrevious write of size 4 at 0x55c2f79772f8 by thread T3 (mutexes: write M508861):#0 sqlite3WritableSchema /home/lewis/Sandbox/Stroika-Build-Dir-Ubuntu1804_x86_64/IntermediateFiles/g++-debug-sanitize_thread/ThirdPartyComponents/sqlite/sqlite3.c:114046 (Test36+0x4a111a5) The conflict appears as follows:testcase( pIn1->flags & MEM_Int ); // READ IN ONE THREAD after write:testcase( (db->flags&(SQLITE_WriteSchema|SQLITE_Defensive))==0 ); IN ANOTHER THREAD NOTE - there ARE MUTEX locks used. But each thread has its own mutex, and TSAN correctly reports this as a (likely) thread bug, that no single mutex is used to protect this data structure.
