I have a bug in the kotlin compiler in that it crashes with the following. How can I narrow it down to which file is causing the problem:
Copy code

If you use gradle there is usually line like 
Error has occurred during compiling file filename.kt
in build log (or smth like that) Not sure about other build system
n
I am not seeing such an error. Unless the build log is somewhere I don’t know about.
d
Can you provide full build log in text snippet here?
Hm, indeed Could you try to run build with 
--debug
option?
n
not much in there…
d
Thanks Most likely it's a problem of incremental compilation @Andrey Uskov [JB] can you take a look?
n
you are right
I disabled incremental compilation and found the problem
d
What was that?
n
I had added a Generic Parameter to a class and hadn’t updated all the usages
d
But there is still a bug in IC. Because compiler should report such error normally and not throwing exception Moreover I'm extremely surprised that exception came from that exact place
n
I am using 
1.7.10
not k2
perhaps it is fixed in a later version
