Hi,
as far as I understand <https://reproducible-builds.org/> this issue
is caused by GCC (and LLVM, ...) default behaviour. It seems to me
as if creating so called "reproducible builds" is quite involved and
comprises setting environment variables as well as additional compiler
flags (and possibly more, I only skimmed the web page).
Assuming that the patch attached to the bug report fixes the reported
issue, I would suggest to add the patch or some functionally similar
adjustments to the Debian package.
Best regards,
Erik
