            Bug ID: 2782
           Summary: CACAO - Internal compiler error:
                    java.lang.ArrayIndexOutOfBoundsException (ECJ race
           Product: IcedTea
           Version: 2.6.3
          Hardware: ppc
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: CACAO
          Assignee: stefan at complang.tuwien.ac.at

When trying to compile gnu-classpath 0.98 (and probably 0.99, haven't tried)
with any version of ECJ (3.7, 4.2, 4.4, 4.5, 4.6M4), I get output like the
following from a CACAO-based icedtea.

1. ERROR in
(at line 0)
        /* DynEnum.java --
Internal compiler error: java.lang.ArrayIndexOutOfBoundsException: 45 at

I know it's a race condition because it works if I manually perform the
compilation under "taskset -c 0". I'm pretty sure it's a CACAO problem because
it doesn't happen with a Zero-based icedtea, IBM's JVM, or a native ECJ built
with GCJ. It also happens with icedtea 1.13.9 so I don't believe it's a recent
CACAO issue.
