Failures don't mean unsafe. If you could exploit those failures that would mean unsafe. Try it on servo! Me & other servo contributors would welcome it.
Don't be so aggressive. If I criticize code, it doesn't mean I criticize people.
I tried to say that language injections (such as C++ libs) make Rust apps more fragile. If my assumption is wrong, and all these failures because of Rust code - I apologize.
I don't know with regards to the failures you saw. For the issues I see & fix most are in rust code.
I didn't mean to sound aggressive, we really would welcome reports of safety issues. It's hard to know if servo /really/ is safer without the hundreds of people trying to exploit it that chrome & firefox have.
Servo should be safer & I believe it's safer but I don't /know/ it's safer.
