possible stack corruption with solaris/x86 ?

[darkshark atnight]

I'm falling behind Vincent now in the solaris stakes :(

When starting a game, it crashes.  Seems the pointer, cvar_t
*showpackets, gets modified somewhere.   In VM_Call() the showpackets
pointer is ok, it points to good
data.  Then after VM_Call() does its vm->entryPoint showpackets is changed.
Debug info below: (using the v230 release)

(Oh mouse doesn't work, keeps itself to the bottom right corner, more
on that later)
Sean.
