OS AND VERSION: Microsoft Windows 10

REPORTED BY: Curtis Clark, Ansys; Bob Ross, Teraspeed Labs

DATE: July 27, 2021

DESCRIPTION OF BUG:
There is a coding mistake due to a missing "else if" in place of "if" on
the third line:

   if (gbAllowAnyVersion || (pHdr->sIBIS_Ver[0] == '6' && pHdr->sIBIS_Ver[2] == '1')) 

of this code sequence in line 647 of hdr.c:

   /* _APT_ */ 
   if (gbAllowAnyVersion || (pHdr->sIBIS_Ver[0] == '7' && pHdr->sIBIS_Ver[2] == '0'))  
    geFileVersion = VER_7;
   if (gbAllowAnyVersion || (pHdr->sIBIS_Ver[0] == '6' && pHdr->sIBIS_Ver[2] == '1'))  
    geFileVersion = VER_61;
   else if (gbAllowAnyVersion || (pHdr->sIBIS_Ver[0] == '6' && pHdr->sIBIS_Ver[2] == '0'))  
    geFileVersion = VER_6;
   else if (gbAllowAnyVersion || pHdr->sIBIS_Ver[0] == '5')  
    geFileVersion = VER_5;
   else if (gbAllowAnyVersion || pHdr->sIBIS_Ver[0] == '4')  
    geFileVersion = VER_4;
   else if (gbAllowAnyVersion || pHdr->sIBIS_Ver[0] == '3')  
    geFileVersion = VER_3;
   else if (pHdr->sIBIS_Ver[0] == '1')  
    geFileVersion = VER_1;
   else if (pHdr->sIBIS_Ver[0] == '2')  
    geFileVersion = VER_2;

This problem has been discovered and fixed by the parser developer.  The
