gdb backtrace

I have been in #plasma talking about this. My gdb backtrace is attached.

bootup works through SDDM, but as soon as I log in I see the plasma 5.9.0 splash that fades. it fades eventually (probably after a timeout), but the background is always black. 

I am on neon dev/stable. qt 5.7.0, plasma 5.9.0.

So this is probably a problem with jit engine of qt javascriptcore. I had disabled memory overcommit to try and stem OOM problems I was having, and this is the cause. Someone on Qt should probably know the engine does not work with vm.overcommit_memory = 2.
