With clang 17 I see the same type of difference, making it likely that some stack alignment setting leaks in from the host architecture. It is going to= be very time consuming to figure out the exact upstream commit(s) that fixed t= his. For now I am doing 13.3-RELEASE-p1 buildworlds with clang 18.1.3 (as it is = in main right now) as host compiler, both in "cross" and "native" mode. I will report back when I have some results there. --=20 You are receiving this mail because: You are the assignee for the bug.=
