StackOverflowException thrown with no recursion

I have a program throwing the StackOverflowException with no discernible source of recursion. As expected of this error, everything dies miserably with no usable logs.

I make heavy use of static classes for specific functionality along with passing certain methods around using Action or Func leading me to believe I may have introduced a loop. While this is a huge problem in my testing environment, I could not reproduce it on my own machine.
