Am I right? One needs to set at least `AddrSize` and `OffsetEntryCount` as callers do use it. Not sure now with the other fields but in such case one would remove them and also from existing `DWARFListTableHeader::extract`. `DWARFListTableHeader::create` should be as much similar to `DWARFListTableHeader::extract` as possible. Maybe we could make some `[nfc]` patches to make `DWARFListTableHeader::Header` smaller but it is now only 16 bytes already so I do not find that much useful. It would be also orthogonal to this patch. ================ Comment at: llvm/lib/DebugInfo/DWARF/DWARFListTable.cpp:54 + + Data.setAddressSize(HeaderData.AddrSize); + return Error::success(); ---------------- ikudrin wrote: > The line looks suspicious because `Data` is a local variable that is > destroyed right after the statement. You are right. Although existing `DWARFListTableHeader::extract` had the same problem from where I did copy-paste it. Filed for it D107470.
