What Does This Do

In Lambda, the inner stack trace is truncated -- stack frames from fileName='AWSLambda.java' are removed. Therefore, in the original code, we would end up with a negative currentIdx, resulting in an error occurring in sanityCheckSnapshotAssignment. This PR adds a fallback to fix the mismatched pointer.

Motivation

Reopens #8849
SVLS-6855
