Minimal test case

generatorrunner is segfaulting on a simple typesystem (reduced from a larger
one). Here is the gdb backtrace:

Program received signal SIGSEGV, Segmentation fault.

Compiling everything with Debug, it gives an assertion failure instead, and a
slightly different backtrace:

ASSERT failure in QList<T>::at: "index out of range", file
/usr/include/qt4/QtCore/qlist.h, line 439
