Could you run it with optimizations? Larry Evans wrote:

Draft version 0.8 contains a makefile for gcc under prj/gcc directory. I compiled the example with gcc from OpenSuse 10.2. I left the executable and object files (for 80x86) in the zip file so I hope some other people can run it in case there is a problem.
What impressed me is how fast the benchmark was compared to Microsoft's compiler. The malloc routine of gcc must be very good.
Larry, what are you trying to run the program on? is it a PowerPC machine? if so, your version may crash due to different endianess (perhaps because pointer addresses are used as bitfields?)...
It's a compaq 4400 (bought 7/12/2002) so its an iX86, not PowerPC. Maybe I just didn't let it run long enough. So for (about 3-5min) I get:
