>Description:
Sun and SGI compilers emit an error on the attached code:

$ CC -V
CC: Sun WorkShop 6 update 2 C++ 5.3 Patch 111685-12 2002/12/16
$ CC -c foo.cc
"foo.cc", line 2: Error: Cannot use int* to initialize int**.
1 Error(s) detected.
$ 

$ CC -version
MIPSpro Compilers: Version 7.3.1.3m
$ CC -c foo.cc
cc-1140 CC: ERROR File = foo.cc, Line = 2
  A value of type "int *" cannot be used to initialize an entity of type "int **"
          .

     int **foo = new (int*)[33];
                 ^
...
$ 

The GNU compiler doesn't.

The Sun engineers insist this is not legal code.
