That's a filename symbol in the debug info. Using a deterministic filename
has potential problems, although I note that it's still fairly
deterministic anyway.

A C compile that uses temporary files will also have symbols that change
this way (usually referring to assembler temporary files). There is not a
lot to be done about this, as you're at cross purposes with the system
linker and with people who want to be able to debug programs.
