For some reason, it seems sysctl vm.mmap_min_addr=0 is no longer enough to make SheepShaver work on kernel 6.5.2-arch1-1 (from Arch Linux).
I now keep getting ERROR: Cannot map Low Memory Globals: Cannot allocate memory. though this worked fine yesterday.
In addition it segfaults if I try to build with direct addressing mode instead (I will investigate that and possibly open a separate bug about it).
