BQN doesn't have keywords but primitive symbols are reserved. It's quite funny how this manages to compile.

C (gcc), 358 bytes

static inline _Noreturn float f(union u);extern _Thread_local _Complex long double*restrict B;main(void){_Atomic register enum {A};typedef _Alignas(unsigned char)struct S;_Static_assert(_Alignof(_Bool),"_Imaginary");do goto a;while(sizeof B);if(1)for(auto volatile const signed short int i;;)continue;else switch(_Generic(0,default:0))case 0:a:break;return;}

Try it online!

Since nobody dared to take on C since this was posted, here's my attempt. It fulfills the "doesn't crash" criteria (though returns an unspecified value from the program).

Disclaimer: I couldn't get _Imaginary to work in gcc and clang doesn't even support complex numbers. Therefore I included the keyword inside a string literal, so that I won't get any unfair advantage against someone who can manage to get it working on some compiler.
