Hi,
I'm running unstable, and did an apt-get dist-upgrade this evening.
The result was a crash in dpkg with the following error message:
apt-get: ../nptl/sysdeps/unix/sysv/linux/fork.c:132: __libc_fork:
Assertion `({ __typeof (self->tid) __value; if (sizeof (__value) == 1)
asm volatile ("movb %%gs:%P2,%b0" : "=q" (__value) : "0" (0), "i"
(((size_t) &((struct pthread *)0)->tid))); else if (sizeof (__value)
== 4) asm volatile ("movl %%gs:%P1,%0" : "=r" (__value) : "i"
(((size_t) &((struct pthread *)0)->tid))); else { if (sizeof (__value)
!= 8) abort (); asm volatile ("movl %%gs:%P1,%%eax\n\t" "movl
%%gs:%P2,%%edx" : "=A" (__value) : "i" (((size_t) &((struct pthread
*)0)->tid)), "i" (((size_t) &((struct pthread *)0)->tid) + 4)); }
__value; }) != ppid' failed.
E: Sub-process /usr/sbin/dpkg-preconfigure --apt || true received a
segmentation fault.

Near as I can tell, this is an assertion somewhere in the bowels of
libc - a nasty place for things to go wrong. The error seems to be
affecting anything trying to do certain type of fork() operations.
Among others, it has taken out apt-get and dpkg :-(
Has anyone (a) seen anything like this (b) got a clue what's causing
it or (even better) know how I might go about fixing this? Right now
the system is still usable for most things, but I don't know how a
reboot would fare, nor how to fix the problem in the areas already
affected.
