Crash in memory_region_init_ram call chain, when --bios command line parameter is presented.

[Alyosha Shevandin]

I would appreciate any clue about the crash.

When I start my custom SoC emulation and the –bios command line parameter us presented, the QEMU processes crashes before the custom code even tries to load the firmware. It crashes in the *memory_region_init_ram* call chain with the follow stack:

#0 0x00005613255a6932 in object_class_dynamic_cast_assert

It seems that the code domain where the crash occurs is unrelated with the –bios command line parameter processing.

I'm using the master branch, commit 13356edb87506c148b163b8c7eb0695647d00c2a
