I updated xen and qemu from xen 4.5.0 with its upstream qemu included to xen
4.5.1-pre with qemu upstream from stable-4.5 (changed Config.mk to use
revision "master").
After few minutes I booted windows 7 64 bit domU qemu crash, tried 2 times
with same result.
In the domU's qemu log:
qemu-system-i386: 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.
Killing all inferiors
In attachment the full backtrace of qemu crash.
With a fast search after I saw the backtrace I found a probable cause of
regression (I'm not sure):

spice: make sure we don't overflow ssd->buf
Added also qemu-devel and spice-devel as cc.
If you need more informations/tests tell me and I'll post them.
