Title:
QEMU crashed when GDB request a big size variable information
Status in QEMU:
Expired
Bug description:
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.
