# The compiler used to emit an invalid DWARF expression for the record
# size, so GDB could not 'print p_record' correctly: a direct 'print
# p_record.i' worked, but iteration over the record fields was broken.
#
# Originally observed at -O2, and the bug was reproducible with just
# -Og.  The DWARF fix covered both optimization levels; not worth
# making guarantees beyond -Og though, so test that.
