The code:

void bub(const inout int other) {}
void main() {
    bub(1);
}

The result:

dmd: mtype.c:1155: Type* Type::addMod(unsigned int): Assertion `0' failed.
/home/ellery/bin/dmd: line 3: 25241 Aborted                 (core dumped)

In mtype.c,
Type::addstorageclass() can result in any combination of const, shared, wild.
But not all possible combinations are considered in Type::addmod.
The missing cases are MODconst | MODwild and MODshared | MODconst | MODwild.
Apparently, if both const and wild are present, wild should be ignored.

So, Type::addStorageClass(), line 1180 should have 'else' added, to make MODconst and MODwild mutually exclusive:


    if (stc & STCimmutable)
        mod = MODimmutable;
    else
    {   if (stc & (STCconst | STCin))
            mod = MODconst;
-        if (stc & STCwild)
+        else if (stc & STCwild)
            mod = MODwild;
        if (stc & STCshared)
            mod |= MODshared;
    }
