# This test shows the importance of not corrupting the order of line
# table information.  When multiple lines are given for the same
# address the compiler usually lists these in the order in which we
# would expect to encounter them.  When stepping through nested inline
# frames the last line given for an address is assumed by GDB to be
# the most inner frame, and this is what GDB displays.
#
# If we corrupt the order of the line table entries then GDB will
# display the wrong line as being the inner most frame.
