What should I grep for when trying to Dustmite this?

`_Z7DtoLValP6DValue` may be suitable. - I don't use dustmite and prefer manual minimization; e.g., by adding `-vv > bla.log` to the crashing commandline. The last lines in that (pretty huge) log file should give you an idea of which function call makes it crash, and possibly even why (it's apparently expecting something in memory which isn't).
Of further help may be a CI build with enabled assertions, downloadable from https://github.com/ldc-developers/ldc/releases/CI.

Is this a C++-symbol?

import core.demangle;
demangle("_Z7DtoLValP6DValue")

returns the same string...

It's C++.

Demangled via

    c++filt -n _Z7DtoLValP6DValue

returns

    DtoLVal(DValue*)
