This is an auto-filled bug because this package does not respect user's CFLAGS.

While SSP is really good for security purpose, I'd expect that with CFLAGS="-fno-stack-protector" the package should not have stack protection.
In this case the file /usr/bin/dirmngr (and maybe some other file from this package) has stack protection.
To check the SSP status you can use:
checksec --file /usr/bin/dirmngr  (from app-admin/checksec)
hardening-check /usr/bin/dirmngr  (from app-admin/hardening-check) 
readelf -sW /usr/bin/dirmngr | grep __stack_chk_fail
