This failure is now visible on other platforms too. Here is the list of platforms where similar javac crash were seen using JDK 6U2 b05.

I also ran the same set of tests with other VM options which did not result in the crash (Eg: -XX:+UseConcMarkSweepGC -XX:+CompileThreshold=100).

Smaller test case:

EVALUATION
This fails all the way back to jdk1.7.0 b03. I don't know why the testing for 1.7 doesn't include running this same test. It sure would be nice if we'd found this earlier.
It looks like it's caused by 20060913073259.nips.unswitch

Here's a command line to reproduce it:
java -Xcomp -classpath /java/re/jdk/1.7.0/latest/binaries/solaris-i586/lib/tools.jar com.sun.tools.javac.Main /net/smite/never/tmp/OpenTypeConverter.java

EVALUATION
Probably wasn't caught earlier as the issue with JTreg (not passing VM options - to javac) was resolved only recently.
