sqlite3 bigmem test catches wrong exception #99659
Description
Lib/test/test_sqlite3/test_types.py has two bigmem tests:
test_too_large_string; andtest_too_large_blob.
Those are skipped unless -M is passed to the test runner so nobody was running those tests until I set up a bigmem buildbot. Running tests on the buildbot revealed two failures:
