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.
