I've seen this before but I'm not sure where the bug is. I guess there has to be a bug in the kernel or in xorg because a userspace program is not supposed to be able to crash the system like that.
If I run it just now on my machine with intel G45 chipset I get this: lseek(3, 73728, SEEK_SET) = 73728 close(3) = 0 munmap(0x7f7bcbd23000, 4096) = 0 *** glibc detected *** strace: malloc(): memory corruption (fast): 0x0000000000e46460 *** ======= Backtrace: ========= /lib/libc.so.6[0x7f1807d80cb/lib/libc.so.6(__libc_start_main+0xe6)[0x7f1807d275a6] strace[0x402119] ======= Memory map: ======== 00400000-00447000 r-xp 00000000 08:02 2065537 /usr/bin/strace 00646000-00647000 r--p 00046000 08:02 2065537 /usr/bin/strace 00647000-00648000 rw-p 00047000 08:02 2065537 /usr/bin/strace 00648000-00656000 rw-p 00648000 00:00 0 00e46000-00e67000 rw-p 00e46000 00:00 0 [heap] 7f1800000000-7f1800021000 rw-p 7f1800000000 00:00 0 7f1800021000-7f1804000000 ---p 7f1800021000 00:00 0 7f1807af1000-7f1807b07000 r-xp 00000000 08:02 10534973 /lib/libgcc_s.so.1 7f1807b07000-7f1807d07000 ---p 00016000 08:02 10534973 /lib/libgcc_s.so.1 7f1807d07000-7f1807d08000 r--p 00016000 08:02 10534973 /lib/libgcc_s.so.1 7f1807d08000-7f1807d09000 rw-p 00017000 08:02 10534973 /lib/libgcc_s.so.1 7f1807d09000-7f1807e71000 r-xp 00000000 08:02 10534951 /lib/libc-2.9.so 7f1807e71000-7f1808071000 ---p 00168000 08:02 10534951 /lib/libc-2.9.so 7f1808071000-7f1808075000 r--p 00168000 08:02 10534951 /lib/libc-2.9.so 7f1808075000-7f1808076000 rw-p 0016c000 08:02 10534951 /lib/libc-2.9.so 7f1808076000-7f180807b000 rw-p 7f1808076000 00:00 0 7f180807b000-7f180809b000 r-xp 00000000 08:02 10534931 /lib/ld-2.9.so 7f1808278000-7f180827a000 rw-p 7f1808278000 00:00 0 7f1808297000-7f180829a000 rw-p 7f1808297000 00:00 0 7f180829a000-7f180829b000 r--p 0001f000 08:02 10534931 /lib/ld-2.9.so 7f180829b000-7f180829c000 rw-p 00020000 08:02 10534931 /lib/ld-2.9.so 7fff10286000-7fff1029b000 rw-p 7ffffffea000 00:00 0 [stack] 7fff103fe000-7fff103ff000 r-xp 7fff103fe000 00:00 0 [vdso] ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall] select(Aborted -- strace locks up Xorg? https://bugs.launchpad.net/bugs/373121 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
