[Bug java/18931] New: jar -> .so optimization problem

["overholt at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When natively compiling Eclipse jars with -O2, I get a compiler error:

$ gcj -fnew-verifier -fPIC -fjni -findirect-dispatch -shared -O2 -o
eclipse/startup.jar.so eclipse/startup.jar
org/eclipse/core/launcher/Main.java: In class 'org.eclipse.core.launcher.Main':
org/eclipse/core/launcher/Main.java: In method
'org.eclipse.core.launcher.Main.adjustTrailingSlash(java.net.URL,boolean)':
org/eclipse/core/launcher/Main.java:0: internal compiler error: in
copy_to_mode_reg, at explow.c:635

Compiling without -O2 (exact same other arguments) gives no errors.

startup.jar can be found here:
