As it also happens to my currently merged mono-6.12.0.122, something must have happened to my build env instead.
I had the same problem. I switched to gcc v12 (from v13) and got Mono to compile and install fine. I guess Mono doesn't like gcc 13.
(In reply to Brian G. Olson from comment #3) > I had the same problem. I switched to gcc v12 (from v13) and got Mono to > compile and install fine. I guess Mono doesn't like gcc 13. Same here. Compiled `dev-lang/mono-6.12.0.182` with `sys-devel/gcc-13.2.1_p20231014`, it fails with the same error/assertion as in https://bugs.gentoo.org/915985#c0. Compiled `dev-lang/mono-6.12.0.182` with `sys-devel/gcc-12.3.1_p20230825`, it is successful. Nothing else changed in the system between the compiler change.
The sandbox failure isn't fatal - it crashes before that, and then tries to invoke gdb to make the log more helpful, and that's where the sandbox violation comes in.
https://github.com/mono/mono/compare/mono-6.12.0.182...mono-6.12.0.199 Please try 6.12.0.199.
mono-6.12.0.199 also fails due to a SIGABRT. These are my logs: https://zxe.io/tmp/Gentoo/mono-6.12.0.199.log https://zxe.io/tmp/Gentoo/mono-6.12.0.182.log https://zxe.io/tmp/Gentoo/emerge-info.txt
Created attachment 874303 [details] mono build logs. Fails due to a SIGABRT. Same logs as in my previous comment. Attached in .tar.xz
Can you try with -O2? Mono is a very crusty codebase and probably riddled with UB.
(In reply to Sam James from comment #9) > Can you try with -O2? Mono is a very crusty codebase and probably riddled > with UB. It works when I use -O2 instead of -O3. Tested with: dev-lang/mono-6.12.0.182 sys-devel/gcc-13.2.1_p20230826
