The attached script, which itself does some GC ops, causes Lua
5.4.0/x86-64 patched with the proto loading patches to fail with the
messages:

attempt to call a number value
stack traceback:
        test-str.lua:2: in main chunk
        [C]: in ?

when I forcefully fail allocation #100, which seems to be for one of
the strings (4):

fail_alloc_at: 00000100: failing
00000100 (nil) 4 (nil) 31

Best regards,
