So you're looking for help compiling something called "strelka" using MacPorts
gcc11 on macOS 10.14. And it is failing with this error:

The first question I would have is: Why use gcc? Can you use clang instead? If
so, do that. Clang is the preferred toolchain on macOS.
If gcc is required and that requirement cannot be removed, then you might try
the gcc-devel port to get a development version of gcc that's newer than
version 11. Maybe this is a gcc bug that has already been fixed after version
11. If not, you may have to report to the bug to the developers of gcc for a
fix.
According to this
https://github.com/Illumina/strelka/blob/master/docs/userGuide/installation.md#prerequisites-to-build-from-source
(if that is indeed the same strelka as the one you're trying to compile) only
a C++11-compatible compiler is required, either gcc or clang.
