I compiled a scala source which was generated by another scala program. then the scala compiler crashed with exception:

I tried it on my osx 10.11.6 and my centos 7.2 linux box.
the result is the same:Crash!
The scala source code is 32m byte or 680k line. and it was compiled almost 10 hours until the compiler crash.

@lrytz said:
Without a reproducible example, this is unlikely to get fixed. Even then, given the enormous compile time.. I think the right approach is to re-structure that code, even if it's generated.
