Hello Newb Here,

When running a terraform plan I receive a !!! TERRAFORM CRASH !!!

Troubleshooting:

1. Upgraded to most recent version
2. Restarted host
3. It appears if I remove the terraform.tfsate file I can successfully run terraform plan

Original version Terraform v0.7.3 Upgraded to Terraform v0.7.7

Looks like this issue was open in October 2016. Will this issue be address? Is there a workaround?

Hello!

Looking at the crash logs, and judging from the nature of the issue, I think this should be fixed now that #129 has been merged. If there is anyone watching this issue that has the capabilities to build a custom provider binary can give it a go, that'd be great.

If course, if this does not fix this issue specifically, please open a new issue and reference this one.

Thanks again and sorry for the delays!

Hi guys, This is yet not fixed in 11.2 with Openstack provider crash.log

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform. A crash log has been placed at "crash.log" relative to your current working directory. It would be immensely helpful if you could please report the crash with Terraform1 so that we can fix this.

When reporting bugs, please include your terraform version. That information is available on the first line of crash.log. You can also get it by running 'terraform --version' on the command line.
