** [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"
TRST OFF;
ENDIR IDLE;
ENDDR IDLE;
STATE RESET;
STATE IDLE;
FREQUENCY 1E6 HZ;
adapter speed: 1000 kHz
TIR 0 ;
HIR 0 ;
TDR 0 ;
HDR 0 ;

SIR 10 TDI (03ff) ;
SIR 10 TDI (03cb) ;
SIR 10 TDI (03d4) ;
RUNTEST 100000 TCK;
SIR 10 TDI (03d4) TDO (0010) MASK (0010) ;
SIR 10 TDI (03c5) TDO (0000) MASK (0000) ;
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff \
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff) \
; 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) ; )
