+ 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
+ registers after the call to find_pc_line. You can check this by
+ inserting a printf at the end of find_pc_line to show what values
+ it is returning for val.pc and val.end and another printf after
+ the call to see what values the function actually got (remember,
+ this is compiling with cc -O, with this patch removed). You can
+ also examine the assembly listing: search for the second call to
+ skip_prologue; the LDO statement before the next call to
+ 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.
+
+ Setting val to volatile avoids the problem. We must undef
+ volatile, because the HPPA native compiler does not define
+ __STDC__, although it does understand volatile, and so volatile
