I can reproduce the crashes in the bot's environment.
In the stderr output there is something that can be interesting:
QSGCanvas: Couldn't acquire a GL context.

Strangely enough the tests does not crash on their own. I tried running just the crashy ones from the fast directory but those were not crashing. When I ran all tests from fast/dom then the same tests were crashing that are crashing with the bot.

[Balazs Kelemen]

Here is the first crash log when manually running everything from fast/dom. Unfortunately this is a release build and I cannot make a debug build in this environment because the linker runs out of memory. :(
