14# This file attempts to check the library in an out-of-memory situation.
15# When compiled with -DMEMORY_DEBUG=1, the SQLite library accepts a special
16# command (sqlite_malloc_fail N) which causes the N-th malloc to fail.  This
17# special feature is used to see what happens in the library if a malloc
18# were to really fail due to an out-of-memory situation.
