Setting GOFLAGS to the following value make it run properly.

GOFLAGS=-ldflags=-extldflags=-Wl,-ld_classic make test

seen on the following issue: golang/go#61229 (comment)

As mentioned in golang/go#61229 (comment) as well, those are just warnings, not errors. Therefore, even if you see those messages in Kueue, they are not crashing the tests.

NOTE -- please read

If you see lines starting with ld: warning but not other outputs, they are just warnings, not errors. You should still get a working binary, if there is no other output. Please only report if you see a link error, or a broken binary, or a warning that is not mentioned in the "warnings" section below. Thanks.

See #61229 (comment) for more notes about malformed LC_DYSYMTAB warning. Thanks.

thanks @IrvingMg

You are correct, they are not crashing; I was thinking it was crashing, but they are just in error in my case:

@akram Yes, the malformed LC_DYSYMTAB warning has been discussed by Go team golang/go#61229 (comment) as well.

A note about the malformed LC_DYSYMTAB warning: take a look at the object file name that is warned on:

• if it is .../go.o, it is the object of the Go code. This is already fixed in recent versions of Go 1.20.x, 1.21.x, and 1.22.x, and should not appear with an up-to-date version of Go.

• if it is .../00NNNN.o with some 6-digit number, it is a C object.

  • if you pass -race and you're using Go 1.22.x, it is probably the race detector's C code, as mentioned above cmd/link: issues with Apple's new linker in Xcode 15 beta #61229 (comment)
  • otherwise it is from user C code

The warning on the race detector C object is not really a bug in Go. Maybe we can fix in the upstream TSAN (also see #61229 (comment)). To work around, you could try

• passing -ldflags=-extldflags=-Wl,-ld_classic to force the old Apple linker
• passing -ldflags=-linkmode=internal to force using Go linker to do the whole linking (although it is not guaranteed to be able to handle all C objects)
• also, an IDE should NOT treat warning as error by default.

Thanks.

So, as this is a non-issue, I wouldn't consider it as a Kueue bug.
