 When compiling with only -Os I get:
 
 Exception in thread "main" java.lang.NullPointerException
    at Test.foo(java.lang.String) (Unknown Source)
    at Test.main(java.lang.String[]) (Unknown Source)
 
 But adding -g (or just removing -Os) I get:
 
 lkasjdfasdf
 lkasjdflkasjdfasdf
 lkasjdflkasjdflkasjdfasdf
 lkasjdflkasjdflkasjdflkasjdfasdf

 Seems that -Os is broken (both in gcc 3.2 and on the 3.3 branch.
 But specifying -g to add ebug symbols seems like a workaround
