      elf2dmp utility is used to convert QEMU memory dumps to Windows kernel dumps.
      eld2dmp fails to handle some of the Windows 11 memory dumps.

      Main reason:
      pdb.c has the following check:

      if (symbols->stream_index_size != sizeof(PDB_STREAM_INDEXES))

      { err = 1; goto out_symbols; }

      This Windows 11 kernel PDB fails the check: https://msdl.microsoft.com/download/symbols/ntkrnlmp.pdb/ee6818ebc82f1f08ba8ebb2fd12196c01/ntkrnlmp.pdb

      The check code is taken from Wine: https://github.com/wine-mirror/wine/blob/master/tools/winedump/pdb.c

      Earlier, symbols->stream_index_size was 22, now it is 24.
