"could not create compact unwind for _julia_Dict_16937: stack subq instruction is too different from dwarf stack size"

[fingolfin]

On macOS 10.14.6, I've started to get these warning when building Julia, at the very end:

$ make
...
    LINK usr/lib/julia/sys.dylib
ld: warning: could not create compact unwind for _julia_Dict_16937: stack subq instruction is too different from dwarf stack size
ld: warning: could not create compact unwind for _julia_Dict_16945: stack subq instruction is too different from dwarf stack size
$

This also happens in the release-1.7 branch, but not in release-1.6, and also didn't happen like a month or so ago.

I also see this when building Julia master on macOS, specifically on an Intel Mac.

Does any of the advice here look helpful for this? https://stackoverflow.com/questions/39598302/ld-warning-stack-subl-instruction-is-too-different-from-dwarf-stack-size-on-os

IIRC on slack @vtjnash identified that the function causing this message was an anonymous function within Pkg.precompile

As someone both suffering this issue and perhaps responsible, I'd appreciate any help in fixing or at least further diagnosing this.

I have not seen this in a long time so I assume it is resolved
