 I am now unable to replicate the original problem using
 the files that i saved and what i believe is the original compiler.
 (It did happen, i'm not really crazy).
 Send this to the Journal for Unreproducible Phenomenom i guess.
 Close the issue...
 Thanks,
 Ted Merrill

 Ted,
 
 I'm sorry I've not been more pro-active on this, I've been overloaded with 
 other issues recently, plus I was on sabatical late last year.
 
 It is a bit difficult even for me here to accept code that might be 
 considered confidential (our lawyers would probably have something to say 
 about it unless there was some form of legal agreement in place).  
 However, I don't think there is any need, since I suspect that I already 
 know what the basic problem is here.
 
 If the problem is what I think, then I believe the latest CVS copy of the 
 compiler has a fix for this bug installed now.  I would be grateful if you 
 could find a chance to check it out and try it on your problem code, 
 please let us know how you get on, then we can close this report.
 
 R.

 I don't need support (at least not at this time), i was just trying
 to improve the compiler.
 The MAINTAINERS file doesn't say who is the maintainer for ARM
 but does still list Richard Earnshaw.
 Since he hasn't commented on this bug, perhaps he is no longer the
 maintainer?
 I'm copying him anyway, but i think past attempts to communicate
 to him directly have not succeeded.
 Thanks
 Ted Merrill

 I did spend some time trying to provide a short test case but was unable to.
 And in fact i have not seen this bug anywhere else but from this one
 fairly complicated source file.
 I worked around the problem by a adding in a local variable instead
 of working directly off of an element of an auto array.
 (The fact that i haven't seen this problem again is probably due largely
 to the fact that we generally avoid auto arrays due to small stack sizes...
 so maybe it isn't such an obscure corner after all.)
 
 I can send you the .i (preprocessed) file and the resulting .s file
 (and the error messages) but i have to have some assurance of
 privacy (not a guarantee) since the files could be considered sensitive
 (although they are hardly the company's crown jewels).
 I.e. i can't post it in the bug database.
 
 Thanks
 Ted Merrill
