I've compiled all of libc, libg++, ld.so, perl, tcl/tk, linux-2.0.30, etc. etc. using 2.7.2p snapshot 970628 most of these with -O2 and haven't had ANY problems that I can attribute to the compiler. Ocasionally I'll get a compiler error and will have to compile A SINGLE FLIE with the standard gcc 2.7.2.2 but I think with beta compilers you should EXPECT some of this.
