Hey all,
I seem to have found a crash that is 100% reproducible in SQLite 3.6.5. I'm
managed to make a reduced test case in a C file that can be found here:
http://files.shawnwilsher.com/2008/11/12/test.c
The file is compiled with the following command:
gcc sqlite3.c test.c -DSQLITE_SECURE_DELETE=1 -DTHREADSAFE=1 -DSQLITE_CORE=1
-DSQLITE_ENABLE_FTS3=1
The program crashes when we try to commit the transaction with the following
stack trace:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
