repro cases for optlink crashes

[Benjamin Thaut]

What is the ideal repro case for a optlink crash?
Are the object files enough or is a reduced sourcecode repro case preferred?
If a reduced sourcecode is required, is there a way to make optlink 
crash with a console message instead of the usual popup window? The 
popup window makes it difficult to reduce the crash.
