Less complicated reproducer, courtesy of @mheon on IRC:

$ podman run --rm --label 'true="false"' alpine true
Error: invalid argument "true=\"false\"" for "-l, --label" flag: parse error on line 1, column 5: bare " in non-quoted-field

[eparis]

do you need to specify --label multiple times, or do you expect people to use it as a CSV. If 'as a CSV' that's what you have and 'true="false"' isn't a valid CSV. If you want people to have to use it multiple times I'm guessing you want a StringArray, instead of a StringSlice.

We use --label multiple times.

Fixed in master.

Does this fix also need to be applied to --env? Slight modification of your reproduction above:

$ podman run --rm --env var='true=\"false\"' alpine true
Error: invalid argument "var=true=\\\"false\\\"" for "-e, --env" flag: parse error on line 1, column 10: bare " in non-quoted-field

[mheon]

2717 fixed --env as well
