I'm reasonably confident but not yet certain that building with gcc 11 works. I see that fedora 37 built glibc 2.36 with gcc 12 without hitting this issue, so it's possible it's the result of some Ubuntu-specific gcc issue but I'm not really sure. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 7+ messages in thread
