<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Some debugging prints in os_file_author
When running CI on linux, there's a SIGABRT:
```
ISSUE.127: 1 assertions passed, 0 failed.
buf2 = 0x807e500, size 1024
malloc(): invalid next size (unsorted)
| Execution error:
|
Error in function UNIX::SIGABRT-HANDLER: SIGABRT at #xF7FC6559.
|
ISSUE.130: 1 assertions passed, 0 failed, and an execution error.
```
But I don't have this problem running on the same linux box. So I
have to do this the hard way using CI and prints to figure it out.
