Hello,

with gcc 3.3 branch (20030524), the compilation _lshrdi3.o no longer hangs. Do you still have a 
problem compiling io-inst.cc? If so, can you please include preprocessed source of that file? 
Thanks,

Dara

Joel,

now that the bootstrap no longer hangs earlier on, can you send the preprocessed source that's 
causing the ICE? Thanks,

Dara

Confirmed with gcc 3.3 branch and mainline (20030708). Can be  
reproduced with cross cc1plus. ICE occurs at any optimization level (-O0 
included).

My testcase was corrupted uploading :-( Will submit a new one once mainline builds again.

Reduced to:

/* Use ./cc1 -O0. */

struct s {
  char c;
};

struct s
foo (char c)
{
  struct s s = { c };
  return s;
}

Replacing char with int will not produce the ICE.

Looking (debugging) at this, this looks like a target problem.

This patch fixes the ICE for me, can you try to see if fixes for you and then submit it:

I caught this problem while building random cross-compilers in a GCC 
testing patch a long time ago.  I do not have an MCORE so if you think 
it is fixed, then I have to agree with you. :)

 From my perspective, if it works for you, it needs to be comitted.
