Same problem here, but with version 1.0.0~beta1-1 (from Debian 12 package).

Diff runs fine but then, as soon as I close the diff (without applying it), pgmodeler systematically crashes (and freezes).

@pms967 @darko1979 Hi!

A sample database in which the crash happens will help me a lot to find out what is going on! :)

Sure thing. How / where can I send you the .dbm file?

BTW: run from the command line, right before crashing it writes: “corrupted double-linked list”.

Edit: if I press "Cancel" before "Close" I get this message instead:
“double free or corruption (!prev)”

I doubt that's much useful, though. :-)

First time I reported this issue I tried creating a sample schema that caused it because I could not attach the schema that I was working on (it was not mine to share). But I was not able to create it and I gave up.

This time I managed to create a schema (with all randomized names) that will produce the issue. Sometimes it would happen that the same schema will crash pgmodeler and then when I try it again it does not.
Attached schema crashed pgmodeler 1.1.6 twice in a row.

Attached file is a database dump, just rename it to test1.sql and restore it. Then create another empty database called test2.
In pgmodeler choose diff and select to compare test1 and test2. After diff is complete click cancel and then close. Pgmodeler should crash.

Update: I have locally rebuilt (on Debian 12) pgmodeler (1.1.5) using the source deb package from Debian unstable (that is I "backported" the Sid package). Just in case I've also deleted the old config files and directories under my home dir before starting the new version.

Now the crash no longer happens (using the very same project file and live DB, of course).

While it may be that the problem was somehow fixed in the newer release, I suspect that the problem may have been caused by an update of some of the pgmodeler dependencies, and what solved it could have been the fresh local rebuild rather than the newer release.

This because the crash problem appeared only recently, all of a sudden. It did not manifest itself previously, despite using the same pgmodeler version (1.0.0~beta1-1) on the same system, also working on the same project (though not exactly the same, as meanwhile I had made some minor changes here and there).

Hope it helps.

Crash still happens on v1.2.0
Tested with the sample I provided on my previous comment.
