When building with '-D_FORTIFY_SOURCE=2' in the CLFAGS/CXXFLAGS the build fails, when the flag isn’t present the build doesn’t fail. I found this issue (http://llvm.1065342.n5.nabble.com/llvm-dev-Thin-LTO-llvm-build-td100633i120.html) leading me to it.
Created attachment 502690 [details] lzma /var/tmp/portage/sys-libs/compiler-rt-sanitizers-4.0.1/temp/build.log
I have this bug again on 5.0.1 btw.
I have the same problem with 8.0.1. -D_FORTIFY_SOURCE=1 doesn't work either.
I have the same problem with 10.0.1. FYI: CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer -frename-registers -fstack-clash-protection -D_FORTIFY_SOURCE=2"
btw https://bugs.llvm.org/show_bug.cgi?id=47163 seems to be related.
I can build it with GCC hardened
