   Eric and I have been tracking down a problem that we suspect may be a
   compiler induced bug.  Just to have some more data, could some folks
   comment on these questions:

   1.  Have you run the ttcp network demo test on your target?  Specifically
       the problem appears to be when transmitting from the target.

   2.  What compiler version are you using?  

I ran the ttcp test a while ago.  I was using egcs 1.1b for the i386
target, probably with no optimization.

If it really is a compiler bug, that sort of question probably isn't
going to help much.  There are too many ways that code can vary.  I
mean, even if you are using egcs 1.1b without optimization, the fact
that it worked for me doesn't prove that your problem isn't a compiler
bug, since your sources are probably not precisely identical to mine.

My experience is that if you're not using any gcc extensions, such as
long long or inline assembler, then it's probably not a compiler bug.
They aren't all that common.
