dumpregs Segmentation fault #188

Closed Tom-Newton closed 3 years ago

Tom-Newton commented 3 years ago

Describe the bug After running my C program on sunflower it seems to run fine but after it finishes running dumpregs causes a Segmentation fault partway through.

issue.zip

To Reproduce Steps to reproduce the behavior:

  1. Download the .zip file above then run the sunflower with the run.m from the zip file.
  2. This should run without error.
  3. Run dumpregs this should show part of the dump then show a Segmentation fault error message.
