I am probably late on this, but Ian is right : with pcc-based compilers,
functions returning struct's use a common zone (called __StRet on sysV68),
that, of course, as different sizes depending of the size of the returned
struct.  Yes, I know, those functions are not reentrant, but many useful
programs do not care about that.
