If the Snappy initiative (or any other group of Mozillians) has short-term
plans to evangelize the perf wins of PGO to Linux distros, I agree that we
should leave PGO builds and testing enabled on Linux and further investigate
the mysterious crash in bug 799295. Otherwise, our builds/testing should match
what our users work with on a daily basis thus preventing an unnecessary time
sink for our devs.
Hopefully those involved in the Snappy initiative can help us come to a final
decision here.
Snappy doesn't cover Linux(only Windows).
The majority of our Linux users also do not use any of our builds or
even use the same compiler as we do. By above logic we should completely
stop doing Linux builds, but that's clear not a good idea :)
This should be fixed. There are ways to disable usage of PGO-information
on a per file basis. Someone could land that to sidestep this crash on
the release channel.

We should really get the latter fixed. Disabling PGO for our builds seems like
a step in the wrong direction; the numbers collected in this thread suggest
that it's a major loss.
