Hello everyone. Soc Encounter 7.1 crashes with a SEGV error when I import a Verilog netlist. From the log file, posted below, it appears that the error comes right after the 'setDrawView' command. Strange thing is that a couple days ago, Encounter was running fine and I have not changed version nor added any patch. So, there has to be something in my RHEL 4.3 distro(kernel 2.6.9-67.ELsmp) that is wrong.
Please, do post some ideas if you've came across something similar. It's really strange.
