Double Commander (commonly abbreviated 'doublecmd') is a orthodox-ish, cross-platform file manager. It is not in portage, but there is bug 415029 with an experimental ebuild from source.

The 0.8.3. ebuild builds on my machine, but whenn I try to run the program, it gives me one of:
Code:
[FORMS.PP] ExceptionOccurred
  Sender=EAccessViolation
  Exception=Access violation

A quick check with ldd looked fine so far, I can not find any apparent linking problems.

There is also a pre-made build available, linking to either Qt or GTK. Running this build also gives me
Code:
[FORMS.PP] ExceptionOccurred
  Sender=EAccessViolation
  Exception=Access violation

Since another Bugzilla user can build and run it just fine, there apparently is a dynamic linking problem on my machine. I just don't know where to start to track it down. As far as I can see I have checked all referenced files and libraries with ldd for inconsistencies, and found none that way. Any hints would be greatly appreciated.
