Compiler internal error?

Hi --

After upgrading to IntelliJ12 I've started experiencing errors while building:

Compiler internal error. Process terminated with exit code 1

with no other details. The IntelliJIdea12 log shows the following:

2013-01-07 12:07:37,317 [3713112]   INFO - ij.compiler.impl.CompileDriver - COMPILATION STARTED
2013-01-07 12:08:55,291 [3791086]   INFO - lij.compiler.impl.CompilerUtil -  COMPILATION FINISHED; Errors: 1; warnings: 0 took 77977 ms: 1 min 17sec

FWIW from a terminal window sbt compiles with no problems. I'm running Idea 12.0.1 on OS X Lion and version 0.7.62 of the Scala plugin; the Scala Compiler preferences have "Run internal server" selected.

Is this a bug, a misconfiguration, or something else?

I've had this problem occur again with 12.0.2 Ultimate. Interestingly, rebooting solved the problem--ouch! I'm curious whether anybody experienced similar behavior wrt reboots? At any rate I welcome suggestions for debugging to figure out what's going on.
