+ change the values of the fields of val. It extracts the elements
+ into registers at the top of the block, and does not update the

+ it is returning for val.pc and val.end and another printf after

+ find_pc_line loads the address of the structure which
+ find_pc_line will return; if there is a LDW just before the LDO,
+ which fetches an element of the structure, then the compiler
+ still has the bug.
