I've forwarded the issue to the XeTeX maintainers [1] and got a statement:

<snip>
 From a quick look at the log, it seems that the ICU headers on that 
system are incompatible with this compiler version (or with the 
particular compiler options being used):

/usr/include/unicode/localpointer.h:559:26: error: parameter declared ‘auto’
   559 | template <typename Type, auto closeFunction>

I think this usage of auto was a C++17 feature, so perhaps -std=c++17 
would help?
</snip>

For now I can confirm that adding the "-std=c++17" flag solves the 
issue, it replaces "-std=gnu++11".

Could you contact ice upstream for this? Thanks!

Hilmar
