commit 13fe20de0088216a1f71a669050199447c5b3217 Author: Georg Koppen gk@torproject.org Date: Sun Aug 30 05:31:59 2020 +0000

Bug 40002: Fix Linux ASan builds for ESR 78

We make the ASan build a first-class tor-browser-build citizen as well. Additionally, we clean the .mozconfig file up so that we have a ASan build without the `--enable-debug` and `--enable-test` options. This makes it more usable for hunting memory corruption bugs. We can think about separate debug builds that have all the assertions etc. enabled if we find that part useful. --- projects/firefox/build | 1 - projects/firefox/config | 2 +- projects/firefox/mozconfig-linux-x86_64-asan | 45 ++++++++++++++++++++++++++++ rbm.conf | 4 +++ 4 files changed, 50 insertions(+), 2 deletions(-)
