to reproduce build qemu with following options:
./configure --enable-debug --target-list=x86_64-softmmu
and run qemu in tcg mode with install image from msdn as following:
qemu-system-x86_64 -m 1G \
-cdrom en_windows_10_enterprise_n_version_1607_updated_jan_2017_x64_dvd_9718069.iso
It seems to be affecting Windows x64 variants only.
Assert also happens with WinEnt 8.1/WinServer 2003 Ent x64
