I just updated GNU ARM Eclipse QEMU to 2.5.1 and initially I had some problems, main() failed quite early, in the first call to `find_default_machine()`.
After several debug sessions, I identified the problem to be a null pointer when a referred interface is not defined. In my Cortex-M specific configuration, `arm/boot.c` was not included in the build, but TYPE_ARM_LINUX_BOOT_IF was referred by TYPE_ARM_GIC_COMMON, the parent of my NVIC object. I guess the problem is in `object.c:type_initialize()`, which does not check the pointer returned by: `TypeImpl *t = type_get_by_name(ti->interfaces[i].typename)` and calls `type_initialize_interface(ti, t, t);` with the null pointers. Normally an assert would be enough, but I don't know exactly which of your asserts better fit here, so I would abstain from submitting a patch. Regards, Liviu
