Well, I really don't see what's going on here.

It may be an issue with qemu_anon_ram_alloc

@VisualEhrmanntraut

Yeah, it seems to be failing to allocate that memory region for some reason. I don’t understand why that would be the case though, potential upstream bug?

Depending on the used compiler quite a few.
What Windows version, architecture and compiler are you using?
How many cores and how much memory has your system?
I'll try to reproduce it in a VM.

How many cores and how much memory? Where did you sourced the compiler? Are you running an unmodified copy of master?

Original copy wont work. bzero is unavailable on windows and there are some other compatibly issues.

I compiled with the regular way to compile qemu

Chris cannot replicate this dram error with latest commit, but emulator also does not run, seemingly because of a bug with the kernel allocations (device tree is invalid). also, even if we fix this you can't install iOS because the companion uses a UNIX socket to connect to the virtualised iPhone
