An example of a file for which pulseview crashes

The attached vcd crashes pulseview. It is valid for GTKWave.
Comment 1 Gerhard Sittig 2023-07-26 08:04:31 CEST 
Most probably a duplicate of bug 1168. The attached file has 447 channels 
which is more than 64. The CLI application can handle the input file, so 
it's not the VCD format and neither its generator.

  $ sigrok-cli -i simx.vcd --show
  $ sigrok-cli -i simx.vcd -O ascii:width=2000 2>&1 | less -S

There could be other reports of that Pulseview channels limit. I suggest 
you find the most appropriate of them and reference it here, and close 
this report here. Its only value is the attached data for reproduction 
while the issue has been identified before.
