there are/were two different variants of this problem:

You are thinking of 64-bit atomics on 32-bit, which are supposed to be 
fixed in the upcoming GCC 16 and after the removal of armel affects only 
non-release architectures.

riscv64 had this problem with 1-bit atomics, which was fixed in a 
different way in GCC 14(?).

The riscv64 issue does not affect many packages (the 32-bit one does),
I might go through these packages at some point.
