https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: net-mail/dovecot-fts-xapian-1.5.5 overwrites CFLAGS/CXXFLAGS or adds uncommon ones. Discovered on: amd64 (internal ref: guru_ci) NOTE: This QA check is tinderbox-only, there is the list of the flags that should be dropped out, if you think it is a false positive please let me know..

I'm confused. It appears that the added flags (eg: -fstack-protector-strong) are added by upstream's scripts as part of the --enable-hardening configure flag, which is enabled by default.[1][2] However, this code looks identical to scripts in net-mail/dovecot[3][4], however I don't see a bug for that package (nor any addressing of the issue in the ebuild). In fact, I don't really see any bugs with "overwrites CFLAGS/CXXFLAGS or adds uncommon ones" in Gentoo's Bugzilla that have fixes besides one that claims upstream fixed it. (A) I'm not sure how to fix it, (B) I'm not sure that I should fix it, (C) I'm not sure how I suppress it. I could add a "hardended" use flag, but it's not clear if that's an acceptable fix or not. Or if it'll just make a new bug that flags are added when that use flag is on. It seems weird to disable hardening if upstream thinks it should be on by default. (And may even depend upon it in some of their assumptions.)

Hi, that's a it simply than you explained. The goal is that I want to compile with -fno-stack-protector it should work.
