Box		: mips-sgi-irix65
Version		: 4.08.2 Unregisterised ( using mini-interpreter)
Source File	: nfibI.hc
( compiled on a running box  i386-unknown-linux  )

bash-2.04$ ./nfibI		--run in irix
nfibI: fatal error: evacuate: strange closure type 4137

Linux closure-type sequence:		Irix closure-type sequence:
============================		=================================
59 (TSO)				59
59					59
59					59
10 (CONST_NOCAF_STATIC)			10
10					10
33  (IND_STATIC)			4137  (zzz! Max number 64 !)
17  (FUN_STATIC)
33

33
29

Why these special types (33,17) crash ?
Where is the info-type stored ?
Is IRIX closure representation-allignment faulty  (char vs int )?

Any suggestions to go on hacking ....
