Tried it 100x times without any change:

---
for i in $(seq 100) ; do dmd -release -run - <<EOF
import core.bitop;

void main()
{
    size_t test_val = 0b0001_0000;

    if(bt(&test_val, 4) != 0)
        assert(false);
}
EOF
done
---

But I can reproduce it with dub:

---
> seq 10 | parallel -j1 -n0 dub -v run --single bitop.d --build=release 2>&1 | 
> grep "exited with code -4"     
Program exited with code -4
Program exited with code -4
Program exited with code -4
Program exited with code -4
