Crashes with ERROR: hash-tree.h:80 #265

Closed syrop closed 3 years ago

syrop commented 3 years ago

duperemove crashes each time I run it. This is the full output:

If the changes are not backwards compatible, you will have to re-create your hash file.

The situation was fixed my creating a new hashfile.

The program actually talks about creating a new file:

Warning: The hash file format in Duperemove master branch is under development and may change. If the changes are not backwards compatible, you will have to re-create your hash file.

I don't know if it's the same. I would like, instead of a crash, a more gentle message, like "please create a new hashfile".

Could you reproduce this crash but when duperemove is compiled with debugging information since It's not possible to determine what exactly went wrong?

syrop commented 3 years ago

It no longer crashes. I can't reproduce it.

lorddoskias commented 3 years ago

In this case I will close the issue, just bear in mind that in the future in order for me to debug a crashing issue it would be best if you could share steps to reproduce or at least share the strack but with duperemove compiled with -g flag so that the full function names can be derived.
