I have db which is version 7.1 (I think) and it was giving problems with debugging code from my 7.4.4m compiler.
I can't find it and may have lost the disk it is on (darn!)
I thought I would try using gdb 6.3 but it (pparently) has issues with mips C++ code.
Then I thought "sod it" I will try to use gcc 4.7 but presto it doesn't work either.
I have gone full round trip and am now left with compiling gdb myself and hoping that it works with gcc 4.7
