I got this error during the arch test but for lack of time I didn't report it. I'm wondering why it was marked stable (our error or it fails on certain arm platform?) it seems that _URC_FATAL_PHASE1_ERROR isn't implemented are you a dev and can pick this up to upstream? Because I can't really :-S Is this using sys-libs/libunwind or sys-libs/llvm-libunwind? Could you try the other for comparison? the initial log is with llvm-libunwind-9.0.1, here's with sys-libs/libunwind-1.2.1-r3:

which seems identical to me?

compressed build log from arm with gnu libunwind
Could you try building with clang (CC=clang CXX=clang++)? This is most likely going to work, as fedora ships their binaries of libcxx{abi} for arm built with clang by default, but I don't have clang emerged at the moment.
Do you really need this for confirmation? I mean, it takes some 20hrs to build it, including a lot of swapping :-S
Well, my guess is that gcc ships and uses broken unwind.h. Ok, I started to emerge clang now, results not before tomorrow. @Agostino Sarubbo if you happen to have clang already available, could you please provide the proof that it works with CC=clang and CXX=clang++ ?

compressed build log with CC=clang and CXX=clang++
seems to work with clang, so can you imagine to introduce a clang use flag just as in compiler-rt, merely to mitigate the problem?
Still an issue with 10.0.1. only the gcc backend is broken, you can use clang as a workaround I'm unable to fix the bug upstream, so it might be a good idea to set clang useflag for mitigation? Still with 11.1.0. (In reply to Sam James from comment #14) > Still with 11.1.0. ...and 13.0.0. |
