Nothing's really wrong, except that it's a no-op: it changes structures
passed by value, so the calling program won't ever see the change.  My 
guess is GCC sees this and tries to optimize out most of the code, which 
makes some of its parse tree invalid later.

If you want to change the structure *and* have it changed in the calling 
subprogram, pass a pointer to that structure.
