Optimized shells fail the following jit tests on my machine:

-m -n -a /home/jimb/moz/repro/js/src/jit-test/tests/basic/test586387.js
-m -n -a /home/jimb/moz/repro/js/src/jit-test/tests/jaeger/bug719918.js
-m -n -a /home/jimb/moz/repro/js/src/jit-test/tests/jaeger/testSetTypedFloatArray.js

I'm running Fedora 17, g++ 4.7.0 20120507 (Red Hat 4.7.0-5).

I configured with 'configure --enable-optimize'.

This test passes on the inbound builds.

The problem is long-standing; I get failures when building both the current inbound tip, and, say, this changeset:
