[Lazarus] How to use Lazrus IDE as a test case?

[Hans-Peter Diettrich]

Currently I want to modify a component, that also is used in the IDE. 
Consequently I want to use the IDE as a test case, covering many issues 
not found in simple test programs. Now I ran into a strange problem:

When I want to debug Lazarus.lpi, it seems to behave properly, but when 
I then rebuild the IDE, it exposes a different behaviour, e.g. hangs on 
startup :-(

I already tried to rebuild the IDE *without* making it the new 
Lazarus.exe, but even then Lazarus.lpi behaves differently from 
Lazarus.new.exe :-(

What can I do, to debug Lazarus.new.exe or equivalent?


BTW, where has gone "Build IDE *with* packages"?
