A 3 day delay doesn't make much sense. The gluten would be digested and out of her system by then.

Has she been to a doctor?

It's called the IgG intolerance and shows up after 24h-72h of eating food that one doesn't tolerate. The difference between intolerance and allergy (IgE) is that allergy shows up immediately.

IgE allergies show up quickly - but many allergy (mast cell) reactions, are not IgE reactions and may take considerably longer to show up (for example, MCAS reactions generally peak in the middle of the night, unlike IgE reactions.)

Our immune system is complex, IgE is just a tiny part of it. Some introductory reading:

MCAS = Mast Cell Activation Syndrome MCAD (Mast Cell Activation Disorder) = MCAS or mastocytosis

It isn't necessarilly that unresonable. For example, when a person takes allergy shots (alergens injected directly into the veins) there will be soreness and swelling days after the injection.

By similar logic, a buffer over-run that doesn't cause your program to crash should cause no issues once the data that was being processed at the time has been freed from memory.
