Hey, I am also getting the same two errors.
[/ppro801/releases/2014.03/PremierePro/UIFramework/Src/HotTimecodeControl.cpp-259]
&
[/ppro801/releases/2014.03/PremierePro/UIFramework/Src/InlineEditText.cpp-140]
I am also editing a documentary and heavily use the Markers window. So it seems that it must be an issue with the Markers.
I tried some basic troubleshooting by uninstalling Premier, and reinstalling it completely. I even updated my operating system in the process, but the problem seemed to only get worse. For a while I could edit in chunks of 10 or 15 minutes before a crash. Now when I open the project, it is crashing 10 seconds after I try and edit anything.
Sounds like an issue that Adobe may not yet be aware of?
