dev-lang/tcl-8.6.11 builds with clang, but the result does not work properly The testsuite fails badly (while it succeeds when built with gcc), and also functionality seems to be broken, see, e.g., https://forums.gentoo.org/viewtopic-t-1143333-start-0.html

I can only reproduce this when building without -D_FORTIFY_SOURCE=2 in my CFLAGS. Do the tests pass for you when adding that?

According to Tcl upstream report (https://core.tcl-lang.org/tcl/info/206e58994f3806ec), this problem is supposedly fixed in Tcl 8.6.12. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=35afbb0f209e57fdb2362550c2c0c0469503a5e8 commit 35afbb0f209e57fdb2362550c2c0c0469503a5e8 Author: Alfredo Tupone <tupone@gentoo.org> AuthorDate: 2021-12-11 21:10:37 +0000 Commit: Alfredo Tupone <tupone@gentoo.org> CommitDate: 2021-12-11 21:10:37 +0000 dev-lang/tcl: 8.6.12 bump
Fixed version is stable.
