The most likely *cause* of this is attempting to write too many characters into a local variable that is a character array. The compiler 'plants' extra information on the program's runtime stack to detect this form of problem - when your program attempts to return from the function, the extra code and data 'planted' on the stack are used to detect if your program's actions have corrupted the stack (the extra characters written into the array will likely have overwritten the function's return address). (longer explanation: https://www.techopedia.com/definition/16157/stack-smashing ) Suggest that you look for places where relatively small local character arrays may be overwritten (beyond their declared length) by too much data.
