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):
http://xenbits.xen.org/gitweb/?p=staging/qemu-upstream-4.5-testing.git;a=commit;h=5c3402816aaddb15156c69df73c54abe4e1c76aa
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.
Thanks for any reply and sorry for my bad english.
