Kind of an odd group to post this question to, but I'll take a shot
at an answer anyway (gnu.gcc.help would have been better).

It's possible that the problem has to do with a disagreement between
your code and the kernel as to how structs are passed; by default,
gcc uses an incompatible method.  If this is the problem, you could
try using -fpcc-struct-return.  From the GCC manual:

`-fpcc-struct-return'
     Use the same convention for returning `struct' and `union' values
     that is used by the usual C compiler on your system.  This
     convention is less efficient for small structures, and on many
     machines it fails to be reentrant; but it has the advantage of
     allowing intercallability between GNU CC-compiled code and
     PCC-compiled code

(Sun's compiler is not pcc-based, but the flag still has this name).
