Just got and built the latest snapshot of gcc 3 -- still broken
Details below

[andy]# arm-elf-g++ -v
Reading specs from /tools3/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/3.0.1/specs

gcc version 3.0.1 20010716 (prerelease)

tried to build the following :

int  main()
{
 unsigned long* foo = new unsigned long[20];
 return 0;
}
