There is no "original" mail other than this thread, really, so you're not left out. I didn't bother to debug it further since it was broken everywhere on every occassion including on /bin/false. Here's the backtrace: Program received signal SIGSEGV, Segmentation fault. thunk_convert (dst=dst@entry=0x7fffffffcbe0, src=0x4000a1f170, type_ptr=0x6051b20c <ioctl_entries+268>, type_ptr@entry=0x6051b204 <ioctl_entries+260>, to_host=to_host@entry=1) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/thunk.c:273 273 (*se->convert[to_host])(dst, src); (gdb) bt #0 thunk_convert (dst=dst@entry=0x7fffffffcbe0, src=0x4000a1f170, type_ptr=0x6051b20c <ioctl_entries+268>, type_ptr@entry=0x6051b204 <ioctl_entries+260>, to_host=to_host@entry=1) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/thunk.c:273 #1 0x0000000060038358 in do_ioctl (arg=274888520048, cmd=<optimized out>, fd=<optimized out>) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/linux-user/syscall.c:3940 #2 do_syscall (cpu_env=cpu_env@entry=0x625a5bd0, num=16, arg1=<optimized out>, arg2=<optimized out>, arg3=274888520048, arg4=<optimized out>, arg5=274901073728, arg6=274888522607, arg7=0, arg8=0) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/linux-user/syscall.c:6281 #3 0x00000000600298b6 in cpu_loop (env=env@entry=0x625a5bd0) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/linux-user/main.c:305 #4 0x0000000060003676 in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at /home/abuild/rpmbuild/BUILD/qemu-2.3.0/linux-user/main.c:4419 (gdb) p se->convert[to_host] $1 = (void (*)(void *, const void *)) 0xbabababababababa which means the pointer has been free'ed already.

As I explained before, you don't get failure reports on qemu-linux-user failures (which is why I think you should use e.g. jenkins or the like for testing qemu). > but this always fails for all architectures and repos in OBS - sometimes > with segfaults, sometimes without - whereas it succeeds with exit code 0 > on my local 13.2 x86_64 system.

Its just a memory management issue, you can install aaa_base-malloccheck (which is always installed in build environments) or you can use more sophisticated tools like .e.g. valgrind.
