MSPM0G3507: linker fill not working

I tried method in this post

and it works.  in screenshot below 0xAA is fill

So I am reporting a bug because this does NOT work.  I do see -Wl,--fill_value=0xAA  added to command line but DOES NOT WORK.

if I remove the "FILL = 0xAAAAAAAA" from the linker script and leave the  -Wl,--fill_value=0xAA  fill value in the linker settings I get this

also tried -Wl,--fill_value=0xAAAAAAAA, no change. Please confirm bug exists.  See below for complete linker command line.

That is wired. I used to think this should work.

I will do a test based on your findings.
