import core.stdc.stdlib;

void doAlloca() pure {
    alloca(8);
}

void main() {
    doAlloca();
}

Error: pure function 'doAlloca' cannot call impure function 'alloca'

I approve of this.

In the meantime a workaround is to use a extern in the module (it's not
@trusted):

extern(C) pure nothrow void* alloca(in size_t size);
