@kolyshkin requested issue #65625 to be considered for backport to the next 1.22 minor release.

@gopherbot please consider this for backport to 1.22, it’s a major regression for runc (it stopped working completely).

[release-branch.go1.22] runtime: x_cgo_getstackbound: initialize pthr…
95389d3 
…ead attr

In glibc versions older than 2.32 (before commit 4721f95),
pthread_getattr_np does not always initialize the `attr` argument,
and when it fails, it results in a NULL pointer dereference in
pthread_attr_destroy down the road.

This is the simplest way to avoid this, and an alternative to CL 585019.

Fixes #67650.
