Hi,

I have been compiling root with GNU c compiler release 3.3 debian
(gcc-3.3 (GCC) 3.3.3 20040214 (prerelease) (Debian))
the compilation proceeded very well without problem and root worked fine at 
first sight. But when playing with trees I got into serious trouble.
Filling and writing a tree in a file worked well, appending to it a also, data 
looked fined, but trying to append again some more (writing a third time)  
resulted in an error that took me a while to understand (because everything 
else wasworking fine). I first thought it was my own responsability, then the 
ROOT APIs but realised the problem was comming from my compiler. I downgraded 
to gcc-3.0.4 and everything's running ok now. I just wanted to mention that 
point.

PS: 
I tried to downgrade to gcc 2.95-4 (debian) but unfortunately I could not 
proceed the compilation untill the end because of an implicit class method 
declaration. Maybe this is comming from my configuration.
- - all this was with root 3.10-2 and 3.10-2cvs
