No plans to address at this time.
The attached hello.c is a typical hello world program. Build it with version 7.4.23 and then 8.3.4 ...
# set path to version 7.4.23 $ cl6x hello.c -z -o hello.out -m hello_7423.map <Linking> # set path to version 8.3.4 $ cl6x hello.c -z -o hello.out -m hello_834.map <Linking>
Look for space after the last character on the line. Particularly in the symbol dump, 8.3.4 has many more trailing space characters. One way to see it ...
$ cat -vT hello_7423.map ... GLOBAL SYMBOLS: SORTED ALPHABETICALLY BY Name ^M ^M address name^M -------- ----^M 00000008 $bss^M 00000008 .bss^M 00000008 .data^M 00000020 .text^M $ cat -vT hello_834.map ...

For more context, please see the related forum thread. In that specific case, the newer map file is about 3X as big.
