Error in using GS (ghostscript) command in Unix

I am sometimes facing issues while using the gs command in Unix.
PFB the explanation of the issue

1. Assume we are using the following command to merge few .out files to make a single .pdf file

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile= ABCD.pdf A.out B.out C.out D.out

2. This command ends up in error as follows (which makes no sense to us)

ERROR: /rangecheck in --cvrs--

ESP Ghostscript 815.02: Unrecoverable error, exit code 1

3. Now the file ABCD.pdf has been created with size of few Kbs. It was found that the file ABCD.pdf is a merged output of files A.out and B.out which meant that there is some issue with the file C.out

4. So now we run the command again with C.out removed from the list as follows and it works without any error and we also get the output ABCD.pdf as merged from A.out B.out and D.out

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile= ABCD.pdf A.out B.out D.out

5. On opening the C.out file looks just fine like others but we really don’t understand what problem is there with this file causing the command to fail. Even the attributes of the file C.out is same as others.
6. Bottom line is that having the file C.out in the list anywhere causes this error.

Any pointers in this regard will be appreciated.
