Thanks for the heads up.  I'll keep an eye on the problem, although 
without a definitive way to reproduce it, it may not be solved.  Plus 
there is always the possibility that the problem has already been fixed 
in the binutils mainline code.

As a matter of interest, does the problem still occur with the gdb 7.1 
sources ?  They are using a newer snapshot of the binutils sources, so 
maybe the issue has been resolved.

Cheers
