sys-apps/busybox-1.26.2::gentoo was built with the following:

(I build system with LTO and I did try to disable it for busybox without change of result

[Comment 1 jy6x2b32pie9 2017-05-06 02:53:01 UTC]

Experiencing same problem in the middle of world rebuild due to move from GCC 5.4.0-r1 to 6.3.0

[Comment 2 fuse809 2017-05-07 19:53:06 UTC]

I experience this bug too when compiling busybox with GCC 6.3.0.

[Comment 3 fhede 2017-05-07 21:36:33 UTC]

I have this bug too when compiling busybox with gcc 7.1.0

[Comment 6 Matthias Maier 2017-05-08 22:32:11 UTC]

It indeed is.

The patch in question has been added to the gentoo patchset for sys-libs/glibc-2.25 which we should keyword at some point.

[Comment 7 Xavier Miller (RETIRED) 2017-06-12 15:56:45 UTC]

same problem with new profile, gcc-6.3.0 and glibc-2.24-r1

[Comment 8 Zoltan Puskas 2017-07-03 01:29:25 UTC]

This actually blocks new installations. After uncompressing stage 3 one has to run emerge -uND world and it breaks on this error.

[Comment 9 David Carlos Manuelda 2017-07-17 19:51:29 UTC]

Temporarily disabling static use flag makes it compile, but I don't know if that has bad consequences. If not, I would suggest hard masking static use flag for busybox for now.

As far as I understand, busybox is the default rescue shell when booting.
Parts of it are copied in the initramfs at kernel/initramfs compile time.
The end result is that you would end up with a non-working rescue shell at the next initramfs rebuild, because libc.so is not copied into the init image and busybox is not statically linked.

As for the bug: running GCC 6.3.0 and glibc 2.24-r3 here. I see that the patch 00_all_0032-x86_64-fix-static-build-of-__memcpy_chk-for-compiler.patch is now applied, but it's not working, busybox still fails at compile time.

Just realized that the patch applied is for memcpy_chk, not memPcpy_chk.

I have attached a patch based on the upstream one that fixes the issue (likely identical to the one applied to 2.25). I can finally compile busybox with GCC 6.4.0 and glibc-2.24-r3. Just drop it in /etc/portage/patches/sys-libs/glibc/.

Can we please backport it for glibc-2.24? Or is glibc-2.25 going to be unmasked soon?

[Comment 12 Fabio Scaccabarozzi 2017-08-06 09:25:47 UTC]

Created attachment 488114 [details, diff]
Fix static mempcpy_chk.

[Comment 13 Andreas K. Hüttel 2017-09-11 10:04:29 UTC]

glibc-2.25 will be stabilized soon.

[Comment 14 Andreas K. Hüttel 2017-10-19 19:26:27 UTC]

Fixed in 2.25
