Compiler issue on AArch64 Linux

[jakobnissen]

This error occurs only on Linux and ARMv8. It works fine on M1 MacOS. Error:

This appears to be the same issue as #352 - however, notice that the error occurs on rust-htslib 0.44.1, where the error ought to be fixed. Maybe the fix didn't get in properly?

@jakobnissen I think it was recently fixed in master: #415

[brainstorm]

And compiles fine with newest CI thanks to #465
