ITPEC FE Morning October 2022 — Question 48 of 80
Stack Trace — a record of active call stack frames used for debugging.
A stack trace shows the sequence of method/function/subroutine calls that were active at the point where an error occurred.
Why not others:
- (b) Stacking/gathering traces left by other programs — stack trace relates to a single program's call stack, not other programs
- (c) Traces left in memory from a stack data structure — confuses the call stack with the abstract data structure "stack"
- (d) Tracing stack data structure used in the program — same confusion; stack trace refers to the call stack, not a stack data structure
Key rule: Stack trace = call stack snapshot at the point of failure, showing the chain of function calls.
