... this happens after several days of mining on NVIDIA RTX 20 series. Difficult to reproduce.

Some time ago I had SIGSEVs bc I accidentally had this line

export GPU_FORCE_64BIT_PTR=0

in my ethminer startup file. Not sure if this helps, I just saw that my SIGSEV output was similar to yours.

@Technologov I run into the same issue w/ my 1080 Ti

I'll build debug and investigate further

same, ubuntu20.04.

Same here: https://paste.ubuntu.com/p/vwF6VFxvQM/

Relevant lib versions on my system: cuda 11.3.0-1 libc6 2.31-0ubuntu9 libpthread-stubs0-dev 0.4-1

Worked for several hours or days before this occurred. I was running a second ethminer-0.18.0 instance on the same machine but operating different GPUs, and it remained functional when the first instance segfaulted. shrugs

This issue appears to be a duplicate of #1937
