Morning. I was building some USDT probes for i386 when I saw registers emitted are 2B wide (ax,bx,cx,etc) even if the size is 4B e.g. 4@ax, 4@bx etc. This is causing a 2B value extracted from the probes instead of the expected size of 4B. I had a look at ./include/sys/sdt.h when I found a comment pointing to gcc.gnu.org/PR80115

I had to revert that %w[id] patch to fix this issue.
