I can reproduce this when trying to merge two reports into one (from jest & cypress) when the coverage reports have entries for the same file. Removing reference to files so that a file record only occurs in one of the reports, fixes the problem.

That's because the size of the statementMap doesn't match the size of s for checkRetriable.ts:

NOTE the value of last entry in s is null which is very abnormal.
Is there a way further tracking down the issue?
