--- Comment #25 from Michael Catanzaro <mcatanzaro at igalia.com> ---
I believe it is three backtraces, to the first calls to IsoTLS::get, and then a fourth backtrace for the crash itself:

(In reply to Milan Crha from comment #11)
> I added some debug prints around the code and I see that IsoTLS::get() is
> called three times before it's initialized, before it crashes.
> Unfortunately, I do not have debug symbols compiled, I'll retry, but no
> promises, because the last time I tried gdb didn't like it. I'll see.

>From the first three backtraces, it's not clear to me if IsoTLS::get is returning null, or if it's returning uninitialized memory. But I suspect it's probably the later, because the code expects and is prepared to handle null in all those places.
