Subject: bug#53005: [PATCH 1/1] gnu: glibc: Preserve "__pthread_key_create" symbol.
Date: Mon, 10 Jan 2022 18:34:26 -0500

Avoid a potential crash in multithreaded applications by preserving the
pthread library's "__pthread_key_create" symbol, used by libgcc to detect the
use of threads in an application.

Fixes <https://issues.guix.gnu.org/53005>.

* gnu/packages/base.scm (glibc)[arguments]: Add "#:strip-flags" with
"--keep-symbol=__pthread_key_create" appended to the default set.
