verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository.

+// Check that NullPointerExceptions thrown from library code are
+// caught. This detects a number of failures that can be caused by
+// libgcj being built incorrectly. In particular, we ensure that a
+// SEGV in native (i.e. C++) code in libgcj is handled correctly.
+
+// Regrettably, we cannot guarantee that Double.parseDouble() will
+// always be native code, or that it will never be inlined. It could
+// be argued that we should add a method to libgcj that will be
+// guaranteed forever to be native, but I'm reluctant to add to the
+// library for the sole purpose of performing this test.
