\[ \frac{\fam0 a}{b} \] For my purposes, should such an issue arise, it is easily resolved by using \frac and so, while this example illustrates a shortcoming of \over and the need for something more robust, it …

It is nearly always best to use the slashed form for fractions in the text:

With amsmath or mathtools you can write dfrac instead of frac, but since dfrac is used for inline fractions, it won't change anything for you in math environments. My workaround is using …
