Could you try with -betterC and see if the error message remains?

The error goes away with -betterC.

Ok, if this is with dmd master it's because recently it was made impossible to
use .tupleof inside C code (long story...), however this seems to have disabled
 use of .tupleof when the C struct is being consumed inside D code as well.

-betterC gets rid of the error which suggests to me that it's something to do with TypeInfo.

It’s on the latest stable branch, commit 714c34ef8629c23751d7071d7dcc1d697708ad13

I just tried with master branch, commit
576ab617f5e84b8782752c1ebf5f5fd4beb1dac0
and the error is not there.

It sounds like it's trying to build the default struct member functions for it.

The problem is in the buildXtoHash() function in clone.d. It adds .tupleof properties, whereas C files don't have such properties.
