As far as I remember my last build of RHIDE was using GDB-6.3. I don't 
remember which version was used in RHIDE-1.5a - perhaps GDB-6.1.1. Both 
these versions are old and most likely the support of new GCC versions 
(like GCC-4.1.2 or 4.2.0) is not expected to be very good.

 From the other side it's highly unlikely that there will be new 
releases of RHIDE. The way how RHIDE uses GDB is a dead end and it's 
only a time when it would fail totally with new GDB versions. I don't 
however know if it is already so with already existing GDB versions as I 
have neither used nor built RHIDE for at least 1.5 years.
