Hi guys.
When trying to compile outside our CI, we're seeing this error:
```

```
We thought it's a dependency issue, but running `cargo clean`, `xargo clean` and deleting both their caches didn't solve the issue.
Do you guys have any idea what might be the issue?

I encountered the same problem and can confirm that it relates to the GCC version. I get the error with GCC 10.1 and 10.2 but 9.3 works fine.
I also got this apparent conflict between the Intel and the Rust SDKs when compiling `unit-test`, even with GCC 9.3:
```

```
Recompiling the *Intel* SDK with GCC 9.3 fixed it for me.

seems multiple `libunwind` are involved. let me investigate.

I started running into this as well after upgrading from Ubuntu 20.04 to Ubuntu 20.10. I haven't looked into the cause that much (changes in GCC 10 maybe?), but it seems it may have been fixed upstream in libunwind v1.5 in [this commit](https://github.com/libunwind/libunwind/commit/29e17d8d2ccbca07c423e3089a6d5ae8a1c9cb6e) (referenced from [a similar FreeBSD bug report](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248699)).
Locally, I just commented out one of the `_U_dyn_info_list` definitions in the SDK, and it looks to be building/running fine so far.
