# GDB Python unwinder and frame decorator prototype
#
# This is a very basic demonstration for how to get GDB to unwind the
# "frametest" example crash in https://github.com/ben-cohen/corelibgen and
# apply a frame decorator to the backtrace.
#
# It needs a recent version of gdb and only works on i386 or x86_64.
# You need to manually fill in the PC value of the crash at "XXX" below!
