Segfault when adding quick and declarative modules to QT variable

When running the attached project's executable in gdb I get the following:

Program received signal SIGSEGV, Segmentation fault.

It appears that the error is caused by including quick and declarative:

QT += quick declarative

This works:

QT += widgets quick

I would have assumed that misconfiguration in the .pro file would cause a compilation failure, not a runtime failure.
