Could you run it outside of the docker if the problem still happens?

Could you suggests which variant should I try?  There are many:
http://cdimage.ubuntu.com/netboot/16.04/
HWE kernel or not?
generic or generic-lpae?
beagleboard or pandaboard or tegra or wandboard?

I have only Raspberry Pi 3B+, I hope it can run the images above from a flash
drive / MicroSD.

I am running Arm and AArch64 tests on docker containers running Ubuntu
Xenial.

Underlying hardware is Thunder X1 or D05 machines.

Re: [Lldb-commits] [PATCH] D63540: Fix lookup of symbols at the same address with no size vs. size

2019-11-18 Thread Omair Javaid via lldb-commits 
Hi Jan,

This is known problem and fix is posted here https://reviews.llvm.org/D70155

Please use cmake argument -DLLVM_HOST_TRIPLE=arm-linux-gnueabihf as a
workaround.

Thanks!
