--- Comment #1 from Ralf Habacker ralf.habacker@freenet.de --- It may be for interest that the same backtrace on x86 looks like this:
Backtrace: 0 __kernel_vsyscall+0xe in [vdso].so 1 0xf751702b in libpthread.so.0 2 0x7bc81c28 in ntdll 3 0x7bc83293 in ntdll 4 0x7bc8aa4a in ntdll 5 NtWaitForMultipleObjects+0x2a in ntdll 6 InterlockedDecrement+0x146 in kernel32 7 WaitForMultipleObjectsEx+0x60 in kernel32 8 WaitForSingleObject+0x44 in kernel32 9 dump_backtrace+0xa6 [/home/ralf.habacker/src/dbus-2/dbus/dbus-sysdeps-win.c:2551] in libdbus-1-3 10 _dbus_print_backtrace+0xb [/home/ralf.habacker/src/dbus-2/dbus/dbus-sysdeps-win.c:2562] in libdbus-1-3 11 test2+0xd [/home/ralf.habacker/src/dbus-2/test/manual-backtrace.c:34] in manual-backtrace 12 test1+0xb [/home/ralf.habacker/src/dbus-2/test/manual-backtrace.c:39] in manual-backtrace 13 test+0xb [/home/ralf.habacker/src/dbus-2/test/manual-backtrace.c:44] in manual-backtrace 14 main+0x48 [/home/ralf.habacker/src/dbus-2/test/manual-backtrace.c:58] in manual-backtrace 15 0x4013e2 in manual-backtrace 16 call_process_entry+0xc in kernel32 17 0x7b865023 in kernel32 18 call_thread_func_wrapper+0xc in ntdll 19 call_thread_func+0x7d in ntdll 20 RtlRaiseException+0x22 in ntdll 21 call_dll_entry_point+0x3fe in ntdll 22 wine_call_on_stack+0x1d in libwine.so.1 23 wine_switch_to_stack+0x2b [/usr/src/debug/wine-snapshot/libs/wine/port.c:60] in libwine.so.1 24 LdrInitializeThunk+0x239 in ntdll 25 __wine_kernel_init+0xa13 in kernel32 26 __wine_process_init+0x193 in ntdll 27 wine_init+0x2c8 [/usr/src/debug/wine-snapshot/libs/wine/loader.c:961] in libwine.so.1 28 main+0x8c in <wine-loader> 29 __libc_start_main+0xf3 in libc.so.6
It starts with
Backtrace: 0 __kernel_vsyscall+0xe in [vdso].so 1 0xf751702b in libpthread.so.0
and ends with
28 main+0x8c in <wine-loader> 29 __libc_start_main+0xf3 in libc.so.6
while the x86_64 backtrace starts at
Backtrace: 0 0xe3b17b7b in libpthread.so.0
and goes beyond the x86 end
26 __libc_start_main+0xf5 in libc.so.6 27 _start+0x29 in <wine-loader> ...
