runtime: panic bsdthread_register error due to anti virus software

Trying to run several Go based tools on my Mac, but consistently get an error.

For example...

> make updatedeps
cd config/ && \
go tool yacc -p "expr" expr.y
fatal error: runtime: bsdthread_register error

runtime stack:
runtime.throw(0x244895)
    /usr/local/go/src/pkg/runtime/panic.c:520 +0x69
runtime.goenvs()
    /usr/local/go/src/pkg/runtime/os_darwin.c:88 +0x62
runtime.schedinit()
    /usr/local/go/src/pkg/runtime/proc.c:164 +0x76
_rt0_go()
    /usr/local/go/src/pkg/runtime/asm_amd64.s:91 +0x114
make: *** [config/y.go] Error 1

...tried different executables, same result.

What does 'go version' print?

> go version
go version go1.3.1 darwin/amd64

> uname -prsv
Darwin 13.3.0 Darwin Kernel Version 13.3.0: Tue Jun  3 21:27:35 PDT 2014;
root:xnu-2422.110.17~1/RELEASE_X86_64 i386


Tried a few different tools, plus just running 'go tool' seems to blow up. Assuming this
is related to some dependencies out of sorts. Any ideas? Need any more information to
help sort this out?

Thanks!

Comment 1:

what's the output of env?
or put it another way, are
you using any software that
works by injecting a dylib
into processes?

Status changed to WaitingForReply.

Comment 2 by berniedurfee:

I don't have DYLD_INSERT_LIBRARIES set. Is there any other mechanism of dylib injection
that I should be looking for?

Tried to see if I could just build Go from source, but get the same failure...

Comment 5 by chris.celebi:

I'm having the same exact issue, only difference is kernel 13.4.

Comment 6:

Discussion continues: https://groups.google.com/forum/#!topic/golang-nuts/HtcZc3wO-rw
AV software is injecting a thread into the process (i'm guessing at startup).

Labels changed: added release-none, repo-main.

Status changed to Accepted.

This happens for me using dtruss. Repro:

go test -c
dtruss -f ./package.test
fatal error: runtime: bsdthread_register error

/Users/jeffall/go/src/runtime/asm_amd64.s:95 +0x116 fp=0x7fff5fbffb08 sp=0x7fff5fbffb00

It is a bummer that I cannot dtruss Go files.

[rsc]

If you build with -ldflags -linkmode=external then you should not get this
error anymore. Whether dtruss actually works at that point is a different
problem, not Go's. (In my experience dtruss jumbles together all the
activity of multiple threads, making the output basically useless.)

[ysmolski]

@bradfitz is this something to be solved by Go team? From the comments above we cannot fix it. Also from #18171 it seems to be about satisfying the antivirus.

[bradfitz]

@randall77, you're now the macOS expert (sorry). Thoughts? Do your latest changes impact this at all?

[randall77]

Yes, this should have been fixed when we moved the runtime to use libSystem for 1.11.
I can run a Go binary under dtruss.
I don't have the kernel in question, but I'm going to assume this is fixed unless I hear otherwise.
