ERROR: Program might be overflowing a buffer in strncat. Common mistake:
ERROR: BAD: strncat(buffer,charptr,sizeof(buffer)) is wrong, it takes the left over size as 3rd argument
ERROR: GOOD: strncat(buffer,charptr,sizeof(buffer)-strlen(buffer)-1)
ERROR: Please investigate and fix.
Problematic file(s) and their linenumbers:
  ssi_boot_globus_inetexec.c: 106
