Hi, I just stumpled on a seg fault while trying to use rdesktop after an update of my pc. I run gentoo 3.16.5 x86_64 and use rdesktop-1.8.3 Log file tells me something like: [ 8221.014342] rdesktop[4670]: segfault at 0 ip 00007feb1deb5b67 sp 00007fff8d069888 error 6 in libc-2.19.so[7feb1de2a000+19d000] [ 8234.595630] rdesktop[4672]: segfault at 0 ip 00007f09df10eb67 sp 00007fff91346278 error 6 in libc-2.19.so[7f09df083000+19d000] [striped unrelated log entries] [10909.885587] rdesktop[26919]: segfault at 0 ip 00007f37cfbf3b67 sp 00007fffc4f79828 error 6 in libc-2.19.so[7f37cfb68000+19d000] [12137.604414] rdesktop[30355]: segfault at 0 ip 00007f8347f7bb67 sp 00007fff12265688 error 6 in libc-2.19.so[7f8347ef0000+19d000] [striped unrelated log entries] [12197.597852] rdesktop[30370]: segfault at 0 ip 00007ff44ea30b67 sp 00007ffffc4c5748 error 6 in libc-2.19.so[7ff44e9a5000+19d000] [12233.678555] rdesktop[30375]: segfault at 0 ip 00007f05f23adb67 sp 00007fff8562ef68 error 6 in libc-2.19.so[7f05f2322000+19d000] [12238.834934] rdesktop[30376]: segfault at 0 ip 00007fc0942ffb67 sp 00007fff15a5e7c8 error 6 in libc-2.19.so[7fc094274000+19d000] This happens with my user and root. As soon as I set 'echo '0' >> /proc/sys/kernel/randomize_va_space' it is possible to start it as root. I activated ASLR in kernel space with this update, so this makes sense to me. Anyway this looks like a bug to me but maybe someone proves me wrong. Can anyone help me fixing this? If this is a bug where should I file it and what is needed? If this behaviour correlates with kernel ASLR, this should be easily reprducible. Anyway any suggestions or questions are appreciated. Thank you in advance Bjoern Stueckenschneider |
