Crash when running Qemu.

[Jean-Christophe DUBOIS]

Hi,

Since the last pull I did this week end on the qemu git tree (master 
branch) I am unable to "start" qemu anymore (It was working OK from git 
master previously).

Traces are provided bellow.

Am I the only one to get this behavior?

jcd@jcd-UX305CA:~/Projects/µCOS/work$ 
../../qemu/qemu/arm-softmmu/qemu-system-arm -machine mcimx6ul-evk -m 
128M -display none -serial stdio -kernel ./OS.elf
double free or corruption (!prev)
Abandon (core dumped)

Running the same command from "gdb" provides the following backtrace.
