<pre>
lldb commands are:
```(lldb) target create --no-dependents build/EFI/BOOT/bootx64.efi --symfile build/EFI/BOOT/bootx64.pdb
(lldb) target modules load --file bootx64.efi --slide 0x7e78b000
(lldb) gdb-remote 1234```
QEMU command is:
`qemu-system-x86_64 -vga virtio --no-reboot --no-shutdown -bios OVMF.fd -drive format=raw,file=fat:rw:build -s`
and im getting this crash:
```
Assertion failed: (func), function CreateBlock, file /usr/src/debug/lldb/lldb-16.0.6.src/source/Plugins/SymbolFile/NativePDB/SymbolFileNativePDB.cpp, line 418
