Pier Angelo Vendrame pushed to branch maint-12.0 at The Tor Project / Applications / tor-browser-build Commits: 1044b8c7 by Pier Angelo Vendrame at 2023-03-30T09:30:10+02:00 Bug 40822: --disable-reloc-section on NSIS stubs. Out binutils version adds the reloc sections by default, but NSIS does not work with them. So, we need to pass a flag to disable them, otherwise users with mandatory ASLR turned on will not be able to install Tor Browser. - - - - - 3 changed files: - projects/nsis/build - projects/nsis/config - + projects/nsis/no-reloc-section.diff Changes: ===================================== projects/nsis/build ===================================== @@ -13,6 +13,12 @@ cd /var/tmp/build/nsis-[% c('version') %]-src # only valid for the Windows linker.
