I get a segmentation fault when a C program allocates

if this is a bug would be greatly appreciated.

No this is not a bug, you are allocating the 8MB on the stack. The stack size on ppc-darwin before 7 is only 512K though the stacksize on ppc-darwin after 7 is 8M, you will still not be able to run the program as there is overhead. You need to either change the stack size limit or allocate it on the heap.
