repeatable crash with vague error message

[liamwhite]

…not sure what else to call it, the abort message isn't giving much context.
Steps:

1. $ git clone https://github.com/liamwhite/dgeom.git
2. $ cd dgeom
3. $ git reset --hard 44474033
4. $ dub test --compiler=ldc2

Output:

$ dub test --compiler=ldc2

Confirmed. The simple way to reproduce it to replace step 4 with

cd source
ldc2 -c geom/bezier_fitting.d

Fixed in master.
