            Bug ID: 2781
           Summary: CACAO - typeinfo.cpp: typeinfo_merge_nonarrays:
                    Assertion `dest && result && x.any && y.any' failed
           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
          Reporter: chewi at gentoo.org
                CC: unassigned at icedtea.classpath.org, xerxes at zafena.se

When running the junit 4.11 and hsqldb 1.8.1.3 unit tests, the java process
aborts with the following.

java: typeinfo.cpp:1449: typecheck_result typeinfo_merge_nonarrays(typeinfo_t*,
classref_or_classinfo*, classref_or_classinfo, classref_or_classinfo,
typeinfo_mergedlist_t*, typeinfo_mergedlist_t*): Assertion `dest && result &&
x.any && y.any' failed.
Aborted

I have seen this with icedtea 2.6.3 + CACAO on ppc and ppc64. I haven't tried
any other architectures. icedtea 2.5.6 works fine, which makes sense as a much
more recent CACAO version was used in the former. Unfortunately this makes
tracking the precise cause difficult.

I was hoping to reproduce it with standalone CACAO but it runs the hsqldb tests
fine and produces a single seemingly unrelated test error (not an abort) on the
junit tests regardless of the version.

I believe this to be quite a serious issue so I will report it upstream.
