cdb reads 1024+19952 = 20976 bytes
which is a 18 byte header + 20957 byte value = 20975 bytes

so it did not read enough to determine that the format is wrong
but it stopped parsing

so it does not do the input buffering correctly

you need to check the code how it parses the input,
if it uses libc functions (e.g. getline) then it might
be a musl bug otherwise it's just a cdb bug.
