QEMU crashed when GDB request a big size variable information
Hello,
My host is Fedora 13. My QEMU version is 0.13.0, I use QEMU with GDB to debug Linux kernel(Version 2.6.36.2).
I use QEMU like this:"qemu -s -S -kernel build/arch/i386/boot/bzImage -hda /dev/zero"
When GDB connected with QEMU, and use gdb command print to look big size variable, the qemu is crash down. for example, when I look a task_struct variable 'init_task'(print init_task ), the qemu produce the below message and exit.
*** stack smashing detected ***: qemu terminated
