I just rebooted the phone and attached to unity8 with gdb: - sudo gdb --pid XXXX /usr/bin/unity8
First strange thing noticed, after typing continue in gdb, I see Threads endlessly being created and destroyed, this never stops: [New Thread 0xa18d2450 (LWP 11331)] [Thread 0xa18d2450 (LWP 11331) exited] repeated continously.. Then I use the phone, call it a few times. Finally it crashes. Gdb shows me: Program received signal SIGSEGV, Segmentation fault. 0xb61d342a in _int_malloc (av=av@entry=0xb62694e8 <main_arena>, bytes=bytes@entry=8) at malloc.c:3351 3351 malloc.c: No such file or directory.

The program no longer exists. (gdb) break Breakpoint 1 at 0xb61d342a: file malloc.c, line 3351. So I believe we are running out of memory because of all these threads being created. I do not know how to determine who is creating the threads or why, but assuming this is the issue. Saw the exact same thing when attaching to system-settings after unity8 crashed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387959 Title: unity8 crash in image krillin rtm 139 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1387959/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
