That's useful - thank you. Michael Van Canneyt mentioend he updated the
documentation for this - where is this usually located? It's not here,
for example: https://www.freepascal.org/docs-html/ref/refsu45.html

About a half year ago I raised a documentation issue regarding that:
https://gitlab.com/freepascal.org/fpc/documentation/-/issues/39304
Bottom line: The behavior is _undefined_. Explanation by Jonas Maebe:

because when evaluating at compile time you may get different results
compared to when it gets evaluated at run time due to architecture
peculiarities).
