Multiple attempts to build and test julia 1.6.2 from source on macOS have resulted in successful builds but recurrent test failures for cmdlineargs.jl. I'm unsure of the significance of these failures. Are they trivial? Should they preclude use of this julia build? There is also a Sockets.jl test failure, but this has been reported in #36986.

macOS Catalina 10.15.7

It is not significant, but sounds odd. Could you try running that test in isolation? e.g.:

$ ./julia --sysimage=`pwd`/nonexistant ; echo $?

From the root of the julia build directory:

% ./usr/bin/julia --sysimage=`pwd`/nonexistent ; echo $?
ERROR: could not load library "/Volumes/ssd500/julia/nonexistent"

Are you familiar enough with lldb to run with lldb -- ./usr/bin/julia --sysimage=pwd/nonexistent and get a backtrace?

This looks like the same cmdlineargs test failures I am seeing on Buildkite. E.g. https://buildkite.com/julialang/julia-master/builds/2666#741b51f6-640a-472f-b1b7-18c4b9ce0b1e:

Not at all familiar with lldb, but I gave it a go.

Ah, MWE:
