Thank you for reporting this, it should be fixed now in the following commit:
commit 0ae79c07257923457914f5e63e19355d7772c624

Generate-cache: comparing signed and unsigned integers is bad
Fixes a bug introduced in previous commit.
min_mip is dt_mipmap_size_t, which is unsigned,
and k is signed. So when k becomes -1, it is
4294967295, which is bigger than any maximal
mipmap size (7), so we have issues...
