I have no doubt that passing -O2 works around the issue, but is this the right fix? Especially since it didn't happen with gcc 14.x, it does seem like a regression, no? Could you make a bug report to GCC? Note that they want the preprocessed source code to be able to easily reproduce. Thanks a lot!
