Yiwei Zhang 74f2c06ca5 venus: workaround a gcc-15 dead store elimination (DSE) bug
No issue with clang or gcc-14.x (or earlier versions). The issue only
shows up since gcc-15.1. The compiler somehow fails to consider those
cs helpers dereferencing the pointer from the pNext chain for reads,
and thus has falsely optimized away the pNext store. This change works
around this with a no-op memory clobber.
