Hi
As the title suggests I'm seeing the stack smashing protections kicking in when I use cmake, at least sometimes. I don't know how often cmake is called in builds.
I've spent a little bit of time trying to debug this but its a bit beyond me. The system was built a bit over a week ago following the raspberry pi build instructions, I used stage3-arm64-openrc-20220320T232720Z.tar.xz
After getting distcc working I moved onto emerging system tools and then tried nodejs - this is where the brotli-1.0.9-r3 package first had the issue. I was able to emerge gdb and take a look, initially attempted to rebuild cmake after finding that generated the core file, this had the same error with cmake stack smashing.
Focused on that core dump and saw /lib64/libc.so.6 involved and used gentoolkit to confirm its in glibc so remerged like so - emerge -va1 =sys-libs/glibc-2.33-r13
That merged fine but obviously didn't fix the issue as really it was just the tools protecting the system as I later realised.
I've tried merging cmake with and without distcc enabled to no avail - though it's failing in the config stage that the pi does unless I'm totally mistaken.
Here's a quick copy of what I'm seeing (for future internet searchers)

I can't rebuild cmake to include the symbols so I don't quite know what to do now, if anyone has advice that'd be most welcome
thanks
