another possibility I tested was to disable optimization by adding
CFLAGS=-O0 to the configure-flags. This creates an unoptimized version,
but that should be fine since it's only for the bootstrap. However, I
noticed that my debug messages from my previous attempt were still
visible when compiling icedtea. I don't know what happened, since
there is at least another classpath version before it.

Even more wonderful is the fact I do not get this error at all when
using CFLAGS=-O0, but I do with your patch. I didn't have any issue
either with my previous attempt with debugging. Could there be other
problems with optimizations in classpath?
I attached my counter-patch :)
