Try to remove GPU_FORCE_64BIT_PTR
parameter
from claymore-dual-miner.
Yes, thanks @neoH ...
export GPU_FORCE_64BIT_PTR=1
worked for me also. No more seg fault.

@rhasce you remove it from the start.bash respectively the start_only_eth.bash or whatever is your bash file named. You can also comment it out:
#export GPU_FORCE_64BIT_PTR=0
from claymore-dual-miner.
The same problem. All settings I've removed from start.bash file and there left only the line for start the miner: ./ethdcrminer64 -epool... and so on
And after that I always catch the error

Removing it won't do anything because it has already been set. I had this issue and just set it to 1 rather than 0 and it started working again.

Does setting this environment variable reduce performance? And is this more of a kludge than a solution?
I'm running Fedora 27 with mesa-vulkan drivers under kernel 4.13.16-302.fc27.x86_64 , have flashed the BIOS of my card, and am pushing 1250/2235 on my 480 8GB (I think Sapphire, I have a few). I'm expecting 28-31 Mh/s, but am receiving 20.5Mh/s. I assume if we're not using 64bit address spaces that means only 4GB of the card's memory can be accessed, but that prrobably isn't an issue since the DAG is around 2.3GB last I checked. So is it the case that mining instructions aren't running at their full bandwidth? That seems far-fetched to me because most instructions in GPUs are closer to 256-bit, right? I'm not a GPU developer obviously.

Vega still not working on Claymore 10.6 on Ubuntu 16.04 ?

ETH: 1 pool is specified
Main Ethereum pool is eth-us.dwarfpool.com:8008
DCR: 0 pool is specified
At least 16 GB of Virtual Memory is required for multi-GPU systems
Make sure you defined GPU_MAX_ALLOC_PERCENT 100
Be careful with overclocking, use default clocks for first tests
Press "s" for current statistics, "0".."9" to turn on/off cards, "r" to reload pools, "e" or "d" to select current pool

BTW, xmr-stak-amd is working just fine for monero, so I know my amdgpu-pro 17.50 is working.
