** [tickets:#102] Segfault in SVF module**

I am getting a segfault when attempting to program a Xilinx Virtex 6 FPGA via
an SVF file. I attempted to use XSVF as well, but openocd xsvf support is
broken.
This is the output I get leading up to the segfault:
svf processing file: "fpga.svf"

;
Segmentation fault (core dumped)
Note that the SVF file is about 60 MB. This error probably stems from a
243,000 line SDR instruction (SDR 119784640 TDI (0000000400000004...60MB
snip...fffffffffff) ; )
