Automated browser-laptop builds sometimes crashing in TP

@bbondy what are those tests? Could I run them? It looks like a corrupted buffer for deserialization.

[bbondy]

they are just tests that start the browser, do some task and then close the browser. They download TP on startup like it is normal to do. So you suspect the file somehow gets corrupted?

[bbondy]

but it also happened I seen on dev channel recently, and so it seems like probably not corrupted data file.

Why does it go inside HashSet deserialize and then back into ST_FIRST_PARTY_HOST deserialize? I am a bit confused about the stack because of that.

[SergeyZhukovsky]

It is all ok to me with a callstack. HashSet is a set of ST_FIRST_PARTY_HOST objects. So it calls deserialize for each object inside it.

[SergeyZhukovsky]

I'm going to try deserialize with an existing .dat file in a loop.

Fixed memory corruption using XCode memory sanitizer. Please try the new version with your tests.
