Artix 7 Route File Loading Seg Fault

[SamuelHo10]

VPR runs successfully with the following command:

$VTR_ROOT/vpr/vpr
$VTR_ROOT/vtr_flow/arch/xilinx/7series_BRAM_DSP_carry.xml
$VTR_ROOT/vtr_flow/benchmarks/blif/2/bw.blif
--flat_routing off
--route_chan_width 150
-j12

However, when attempting to launch the GUI, the program segfaults during the routing load phase.
