[Release-testers] [cfe-dev] [8.0.0 Release] Need help with PR40761: Sanitizers broken on FreeBSD

[Kim Gräsman via Release-testers]

I'm not really in a position to have an opinion :), but it seems it
would be useful if check-.* on FreeBSD didn't hang -- it's hard to
judge the quality of anything if the test suite never finishes. I'm
guessing the sanitizer tests have never been 100% successful on
FreeBSD, but now we don't even get a result.
