Bug Description

I had a terminal open and it suddenly crashed.

Now it keeps crashing every time I open a new one.
It either crashes immediately at opening, or after a few seconds.

Sometimes it crashes and closes immediately (I can see the error appear for an instant, see below), other times it shows the error message and stays open.

Hopefully this will be fixed after reboot.

Here's the error message it shows:

bash: ../nptl/sysdeps/unix/sysv/linux/i386/../fork.c:212: __libc_fork: Assertion `({ __typeof (({ struct pthread *__self; asm ("movl %%gs:%c1,%0" : "=r" (__self) : "i" (__builtin_offsetof (struct pthread, header.self))); __self;})->tid) __value; if (sizeof (__value) == 1) asm volatile ("movb %%gs:%P2,%b0" : "=q" (__value) : "0" (0), "i" (__builtin_offsetof (struct pthread, tid))); else if (sizeof (__value) == 4) asm volatile ("movl %%gs:%P1,%0" : "=r" (__value) : "i" (__builtin_offsetof (struct pthread, tid))); else { if (sizeof (__value) != 8) abort (); asm volatile ("movl %%gs:%P1,%%eax\n\t" "movl %%gs:%P2,%%edx" : "=A" (__value) : "i" (__builtin_offsetof (struct pthread, tid)), "i" (__builtin_offsetof (struct pthread, tid) + 4)); } __value; }) == ppid' failed.

Changing this to confirmed as this is a crasher (a crasher doesn't need to wait for somebody else to confirm, does it?)

After this, I rebooted, and the next boot didn't succeed.
When the Ubuntu flash screen appeared and I was supposed to type the password, it hanged and didn't respond (even the cursor stopped blinking, though the mouse cursor moved)
I hit ctrl+F1 to open a virtual terminal, I entered the user name and password, and even the virtual terminal login didn't succeed.

So I forced hardware power off and booted the system again and now everything seems to work fine.

Please tell me which log files I can upload before it's too late.
