Yes, I tried getUnderlyingType(). Here is the code I have:</div>

</div>
<span style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">When this code is ran on the example I posted, first I get TypedefType, then its' underlying type is ElaboratedType which getNamedType is the RecordType. So this function
is called with TypedefType, then ElaboratedType then RecordType. However when I try to call field_begin function on RecordDecl obtained from RecordType it crashes in clang sources. That's why I'm assuming that I'm doing something wrong here. </span>

Did you try getUnderlyingType()? See<br>
