@bcmills requested issue #43068 to be considered for backport to the next 1.17 minor release.

@gopherbot, please backport to Go 1.17. This test still fails intermittently on the release branch, and the patch to skip for that failure mode is small and test-only.

This will clear a current failure on the linux-amd64-nocgo builder:

Approved. Low risk, trivial change that fixes testing issues.

…g a known GDB internal error

TestGdbBacktrace occasionally fails due to a GDB internal error.
We have observed the error on various linux builders since at least
October 2020, and it has been reported upstream at least twice.¹²

Since the bug is external to the Go project and does not appear to be
fixed upstream, this failure mode can only add noise.
