Exception causing setup() loop?

Just a general question here for clarification.

In my setup() I print out a debug line and then call a function, the start of that function also has a println debug statement. So I would get:

"Setup init running"
"MyFunction started"

and done...

I recently made some changes to that function and now I get those 2 lines repeating over and over. Does this indicate that something fatal is failing inside that function now and causing it to recycle?

It usually indicates memory corruption. Show your code. And no, the problem is not necessarily in that function.

Could be crashing and resetting, who knows. No information gets you wag answers.
