Update: Removing the calls to ioctl removes the crash and makes the module work. I don't know at what cost, though.

Do you mean the two ioctl calls inside the module? Or were there some in your code above that you've removed?

If the former, then I think that things may be improved, if not fixed, by changing 

ioctl($client, 0x8004667e, 1);

to

my $true = 1;
ioctl($client, 0x8004667e, \$true );

[download]

I've certainly had code where a similar change prevented traps in the past. I'm not sure if the same is necessary for the ioctl($client, 0x8004667e, 0); case. I'm still a bit perplexed by the logic in the module, and the need for that latter call?
