Hi all,

I saw the following assert after chaning display resolution. This might 
be the cause, but i am not sure. Threaded VNC is enabled.
Anyone ever seen this?

  qemu-kvm-1.0: malloc.c:3096: sYSMALLOc: Assertion `(old_top == 
(((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - 
__builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || 
((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof 
(struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 
* (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned 
long)old_end & pagemask) == 0)' failed.

Thanks,
Peter

A shot in the dark - does valgrind show anything wrong?

Problem is i cannot reproduce this, but I can try running the VM in 
valgrind and
check if there is any problem.
