[Bug java/17380] [4.0.0 Regression] Bad diagnostic and ICE on valid code...

["daney at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

A simplified command line to recreate the problem:

gcj --encoding=ISO-8859-1 --classpath src  -c src/c/ProblemIsHere.java



For what it's worth, here is a backtrace.  There are several incorrect
diagnostics before the ICE so it is possible that the problem is not in code
that is in the trace.  All of the error diagnostics are incorrect.  This code
compiles without any diagnostics with 3.3.1 and Sun's javac.

It seems to be target independent as I get the same error on a
i686-pc-linux/mipsel-linux cross compiler as well.
