Workaround GCC 11.3 compiler bug

[mdemoret-nv]

Description

Compiling on GCC 11.3 breaks due to this compiler bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103871. Using the workaround in this comment seems to fix the issue.

Tested on 11.3 locally. Changes should be benign. No way to test this in CI without adding GCC 11.3 to the build matrix.
