Clang on armhf

[grigorye]

Hi folks, I'm trying to experiment with build some stuff in Container Station on TS-431P3 (that is armhf/arm32v7).

While everything "works" so far, I got a problem with Clang. It basically segfaults on launch like below:

I tried several (stock) containers like LXC ubuntu/bionic, debian/buster, Docker ubuntu/bionic etc, as well as *different* versions of clang. All the combinations crash like above.

For the reference, GCC etc works without a problem.

So, I wonder if there's something wrong on the host side of the system. I do have some Entware stuff installed there but it's pretty minimal/I'm not sure it causes this thing (no clang or something there, just in case). Other than that, I can't recall anything non-standard on the host side.

Any clues/hints?

Just in case, luckily, pre-built binaries for Clang hosted on LLVM releases page seem to work correctly... So, I wonder whether this problem is specific to Debian/Ubuntu package or something... Still looking for any clues.
