Sure it is.  The instruction in the PR is

$ gcj -findirect-dispatch -shared bork.jar # works
$ gcj -findirect-dispatch -shared -O bork.jar
org/apache/catalina/session/FileStore.java: In class
'org.apache.catalina.session.FileStore':
org/apache/catalina/session/FileStore.java: In method
'org.apache.catalina.session.FileStore.save(org.apache.catalina.Session)':
org/apache/catalina/session/FileStore.java:0: internal compiler error: in
make_edges, at cfgbuild.c:327

This is reproducible on x86_64-unknown-linux-gnu HEAD.
