[Qemu-devel] [PATCH v2 4/4] linux-user: initialize progname with error_set_progname()

[Hitoshi Mitake]

Calling error_get_progname() in the context of qemu-x86_64 can cause
segmentation fault because linux-user/main.c doesn't initialize its
progname with error_set_progname(). This patch adds the
initialization.

Currently, the missing call of error_set_progname() doesn't cause any
problems because qemu-x86_64 doesn't use error_get_progname(). This
patch is a proactive action.
