Barry A. Warsaw added the comment: I've now updated my personal machine to Mojave and cannot reproduce the failure. I'm going to chalk this one up to some weird corporate active directory or whatnot weirdness. I'd still love to know why the code in Python works differently that the

STINNER Victor added the comment: It seems like people have fun with getgroups() on macOS: * bpo-7900 * bpo-16661 * bpo-17557 * bpo-29562 Maybe we should simply skip test_getgroups() and test_getgrouplist() on macOS with a comment listing all these BPO issues. -- nosy: +vstinner

Barry A. Warsaw added the comment: Yep, stepping through Python with lldb, that's what's happening. I know one of my coworkers has been able to reproduce it. I'll chime in next once I upgrade my personal machine and can try it there, since I know it isn't on AD. --

Barry A. Warsaw added the comment: I really have no idea what's going on. I've looked at posixmodule.c and tried to reproduce as best I can in a standalone C program. In both cases getgroups(0, NULL) returns 15. In the standalone version, when I then call getgroups(15, grouplist), I again

Ned Deily added the comment: Yeah. Can you check the header file paths that are being used in your compiler invocation, e.g something like: cc -v -c ... And, while you are at it, the library search path of the test executable: otool -L ./... And anything suspicious in /usr/local/include or

Ned Deily added the comment: It very well could have something to do with Active Directory support. Here's a little getgroups test I used a while back for a previous getgroups issue. You should see something similar in the output depending on the number of groups in your id. If it fails,
