Rustc fails to compile project with PGO

[zamazan4ik]

I tried to optimize the Zen project (source code details are below) with PGO with cargo-pgo.

I expected to see this happen:

The project compiles with instrumentation PGO successfully.

Instead, this happened:

During the compilation, I get the following error: https://gist.github.com/zamazan4ik/176517dd1d5bb7dc07c92e13016dfd8d . Switching C/C++ compilers or using nightly instead of stable does not help - the error remains the same.

In Kobzol/cargo-pgo#44 was found that the error remains if we use raw Rustc compiler with proper PGO flags instead of cargo-pgo.
