I am running into something that is causing my program to segfault at the same point every time it is run. Changing the input parameters doesn't help. I am attaching the valgrind error output is case someone may find that useful.

The program has been compiled for 64-bit using both DMD and GDC with the same results. The backtrace as shown in gdb is at the bottom. Can anyone help?

Thanks,
Jonathan
