-O is using a different kernel that has some optimizations and should run faster but only works for passwords up to a certain length (depending on the specific hashing function). This length is usually around 15 bytes.
If you can't crack a hash with -O that has such a short length there is probably some bug with either the kernel or the opencl runtime you are using.
Can you share the hash that is causing this problem and the full output of the unsuccessful hashcat run?
