Hi,
This fixes the issue I introduced in #276 (sorry for the breakage).
This time I tested not directly with boost, but using compiler explorer. This is the code I tested:
I tried with flags
-Wall -Wextra -Werror -std=gnu++03
and-Wall -Wextra -Werror -std=gnu++23
, and with both gcc and clang x86_64 (trunk version in both cases). There is no compilation error in all these 4 different variants.Compiler explorer link for clang/C++03: https://godbolt.org/z/PhPGsMdoM
Cheers,
Romain
