calling a function from an array access panics #46

Closed TotallyGamerJet closed 2 years ago

TotallyGamerJet commented 2 years ago

This C code panics:

void foo(void) {}

static void (*functions[1])(void) = {
    foo,
};

void main() {
    functions[0]();
}

with error:

panic: expected type must be set
