preporcessed natString.cc
For more than a week, mainline fails to bootstrap on IRIX 6.5:
/vol/gcc/src/hg/trunk/local/libjava/java/lang/natString.cc: In member function
'jint java::lang::String::indexOf(jstring, jint)':
/vol/gcc/src/hg/trunk/local/libjava/java/lang/natString.cc:832:1: internal
compiler error: in queue_insn, at haifa-sched.c:1322
This happens both with the old and the current version of the Alexandre's patch
to haifa-sched.c.
I find the following cc1plus stacktrace:

The problem can be reproduced with included natString.ii and
