Package: qemu-user-static Version: 1:7.2+dfsg-7+deb12u2 Followup-For: Bug #1053101
After building without `--disable-pie` and observing differences and results I suspect the cause is something that is so obvious I missed it! The emulator - when totally static - maps to 0x00040000 itself. Then in the target ld-linux-aarch64.so.1 tries to map a static aarch64 executable to the same address (0x00040000) and since qemu doesn't translate that in any way (could it?) the SIGSEGV occurs because the emulator (qemu-aarch64-static) already uses that address. However... the mmap() documentation suggests it should return -1 and set errno and I'd expect that to be EEXIST MAP_FIXED_NOREPLACE. However #2... those same docs state SIGSEGV when "Attempted write into a region mapped as read-only" and that does make sense if the emulator's .text is mapped there (presumably as PROT_EXEC|PROT_READ and MAP_DENYWRITE).
