Description ephemer0l 2021-03-05 17:39:36 UTC 
I don't know how it might have happened, but I can't for the life of me build glibc on a hardend profile.

Reproducible: Always

Steps to Reproduce:
1.emerge -1 sys-libs/glibc
2.
3.
Actual Results:  
/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /var/tmp/portage/sys-libs/glibc-2.32-r7/work/build-x86-x86_64-pc-linux-gnu-nptl/libc_pic.os: in function `iconv_open':
(.text+0x874): undefined reference to `__stack_chk_guard'

Comment 3 Sergei Trofimovich (RETIRED) gentoo-dev 2021-03-05 18:07:57 UTC 
USE=libssp looks very suspicious and it does move out __stack_* function to libssp if gcc is built with libssp.

Can you post your output of:
1. 'gcc -v'
2. emerge --info gcc

Comment 7 ephemer0l 2021-03-05 20:56:37 UTC 
This looks like my ignorance has bit me, again. I did force on libssp along with ssp... Sorry for wasting time, but maybe someone in the future will find this bug...

Glad it was simple. :)
