Hi Craig,
I must admit that I never have compiled a VM myself, nor used lldb nor gdb for that matter. However, I do have Xcode 7.0 installed on my machine, so I might try.
In the meantime I found out that if I start the VM from the command line I get the following error:
sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory
sqAllocateMemory: initial alloc failed!
That is strange. I have 16 GB physical RAM 9 of which are currently used. That should leave plenty for a 2.66 GB image. And as I wrote it used to work fine.
Time for a restart.
Cheers,
Bernhard
