Sorry for the delayed response, I did try with latest gcc, pahole and the 
required kconfig options enabled but i didnt see the reported issue. Compile just 
ran fine. I am probably missing some other config option.

# gcc --version
gcc (GCC) 14.3.0

Anyways, I am okay with the proposed patch. Thanks!
