Starting Code::Blocks Release 16.01 rev 10692 Jan 24 2016, 10:01:09 - wx3.0.2 (Linux, unicode) - 64 bit../src/gtk/window.cpp(3207): assert "(m_widget != __null)" failed in DoEnable(): invalid window
This worked perfectly in version 13.
rest of the logs are attached.
I cannot reporduce this with the latest version? Can you try a night build and tell me if it still crashes? Can you share the project you're using to reproduce the crash?
OP missing, the batch mode has been rewritten and recent tests on Mint+wxGTK3 work OK
