Hello,
while dist-upgrading from stable to testing I encounterd the following problem, also discussed in
http://www.mail-archive.com/[email protected]/msg08274.html
and treated as bug#226688.
Every program using fork() is thrwoing the assertion:
sh: ../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.
In another thread about this issue I have read that the output of LD_DEBUG=all /lib/ld-linux.so.2 --list /bin/bash could be usefull, so I append it here as well.
For hints about solving this and actually also for hints about how to recover the actual situation (probably restoring the old versions of the libs in /lib? But I did this once and the system wasnt respondiong anylonger) I'm thankful.
Ciao, Frank.
