Description Jacob Carlborg 2015-08-31 07:05:38 UTC 
When I compile Tango use DMD 2.068.1-b2 I get this error (dmd -c tango/core/Variant.d) :

Assertion failed: (id->dyncast() == DYNCAST_DSYMBOL), function toExpression, file mtype.c, line 6894.

It looks similar to issue 14889 but this assertion is at a different location.

Please post the reduced test case in bugzilla.
Comment 2 Jacob Carlborg 2015-08-31 12:01:15 UTC 
This is what Dustmite reduced it to:

fromVararg()
{
    new [types[i].tsize];
}
Comment 3 Jacob Carlborg 2015-08-31 12:05:57 UTC 
And here's a test case with valid code:

struct Foo
{
    int tsize;
}

void main()
{
    Foo[] types;
    new void[types[0].tsize];
}
