Segmentation fault

I'm attempting to run a geometry optimization on a fluoride at the DFT level of theory using the B3LYP functional, ZORA, and ANO-RCC basis set. However I've arrived at the following error and can't for the life of me figure out what it's trying to tell me. The message is:

int_init: internal texas instability possible cando_txs set to always be F

Segmentation fault

Any ideas on how to address this are most appreciated.

Thanks in advance,
Tom
