It's not a linker error, and x86_64 mainline gcc 4.10.0 20140727 fails similarly.
nm bytearraymodel_p.o | grep __warn U __warn_memset_zero_len Linking this object file against libc_nonshared.a (which is where this symbol is defined) generates the linker warning which is turned into an error by -Wl,--fatal-warnings. So a gcc bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1352836 Title: link failure when package is built with -O3 (14.10) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-4.9/+bug/1352836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
