  What is your point? I already said that GCC defines it even though the C standard does not. As per the GCC developers: > Type punning via unions is undefined behavior in both c and c++. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=118141#c13 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=118141#c13

    > One of the GCC developers told me explicitly that type punning through a union was UB in C, but defined by GCC when I asked I just was citing the source of this for reference.
