# This file attempts to check the library in an out-of-memory situation.
# When compiled with -DSQLITE_DEBUG=1, the SQLite library accepts a special
# command (sqlite_malloc_fail N) which causes the N-th malloc to fail. This
# special feature is used to see what happens in the library if a malloc
# were to really fail due to an out-of-memory situation.
# This file contains additional out-of-memory checks (see malloc.tcl)
# added to expose a bug in out-of-memory handling for sqlite3_prepare16().
