> A better question might be: Are you going to fix your code?
Yes [1], but that's besides the point here. I can certainly fix my code, but
that leaves 99% of other software.

Thanks for the workaround.
Will the patches be backported to gcc 8.x and 9.x ?

No, that is not how C++ defines it. As mentioned before C++ does not define
the order of the execution of the operands.

Notwithstanding loopholes in C++ legalese, the expected result is to evaluate
things left to right, just like reading words and sentences.
clang produces the least surprising result

Except when there is an = sign, where you expect the right hand side to be

When the irrelevant template parameter is used (arma_template_test.ii), g++
thinks that value in the following code can't be determined at compile time:

I wouldn't call the method presented in the comments to bug #55800 as a

Reduced test case. Compile with:

g++ b.cpp -c -o b.o -std=c++11
g++ a.o b.o -o prog -std=c++11
