Package: qemu-user Version: 1:5.1+dfsg-4+b2 Severity: normal Tags: upstream X-Debbugs-Cc: d...@cowlark.com
I have a test program for the PowerPC which reliably causes qemu-ppc to crash, apparently on startup. I haven't been able to get it to tell me what it's doing during the crash. The minimal program is: ---snip--- .text .global _start _start: li 3,0 li 0,1 sc # call _exit() .section .bss .byte 0 ---snip--- To reproduce, do: $ powerpc-linux-gnu-as -o test.o test.s $ powerpc-linux-gnu-ld -o test test.o $ qemu-ppc ./test Segmentation fault I believe this is a bug in qemu as the same binary works absolutely fine on real hardware. Removing the `.byte 0` line causes the crash to go away. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.9.0-1-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages qemu-user depends on: ii libc6 2.31-4 ii libcapstone3 4.0.1+really+3.0.5-2+b1 ii libgcc-s1 10.2.0-16 ii libglib2.0-0 2.66.2-1 ii libgnutls30 3.6.15-4 ii libstdc++6 10.2.0-16 ii zlib1g 1:1.2.11.dfsg-2 Versions of packages qemu-user recommends: ii qemu-user-static [qemu-user-binfmt] 1:5.1+dfsg-4+b2 Versions of packages qemu-user suggests: ii sudo 1.9.3p1-1 -- debconf-show failed
