Another factor could be that debug info affects smartlinking. Or leaves symbols

This seems to be the problem. I think adding -g turns off
smartlinking, which then blows up the binary size, I've just tested
with and without (-CX -XX).
Looks like I can "fix" this by passing --gc-sections to ld.
Are there any fpc devs that can comment on why smart linking gets
switched off when -g is passed?
Because Free Pascal doesn't support smartlinking+debug info on most
platforms. The only exception is macOS, where it is actually supported.
Adding --gc-sections to the linker on other platforms will probably
result in broken debug info and is not guaranteed to work. Of course,
you are encouraged to try it and test it, and see if it works, but it
probably doesn't.
Best regards,
