It would be a rare flaw that left a pinhole in copper pipe - they do
happen, but they normally cause splits. It _might_ be an inclusion, that
then gave rise to corrosion.

ISTR a batch of very low quality copper pipes around the early 1970's
with this problem, due to contamination with iron or carbon or something.
Service live turned out to be about 10 years before they were leaking
all over the place.
