@ianlancetaylor requested issue #41702 to be considered for backport to the next 1.15 minor release.

@gopherbot Please open backport issues

This issue can cause any Go program that uses syscall.Exec on macOS to crash during the exec. We should backport the fix (when we have it) so that this will work for older releases.

Approved. This is a serious issue with no workaround.
