User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:63.0) Gecko/20100101 Firefox/63.0 Steps to reproduce: I build firefox with GCC and PGO http://hubicka.blogspot.com/2018/12/firefox-64-built-with-gcc-and-clang.html Actual results: Depending on workload of your machine, sometimes train run is killed MOZ_CRASH(Shutdown too long, probably frozen, causing a crash.) at /aux/hubicka/firefox-2018/release/toolkit/components/terminator/nsTerminator.cpp:219 which leads to incomplete profile data and poorly behaving binary Expected results: watchdog timeout should be set to large value - killing training run would only mask other bugs.
Setting the component, in order to involve the development team. Feel free to change it, if I'm wrong.
