Test case:

• f75f4237a016c9a7ea362cf7557edc6b5076815d20733097a3668f3c7de42577

Bearparser mistakenly detects the beginning of the new section as the Last RVA. However, this section has a mapped size 0 - means, it won't be mapped at all.
So, in reality the Last mapped RVA is the end of the section that was before: 1EE00.
