rakudo-jvm build failure as of 2014-04-27

rakudo-jvm-32-bit-build-fail

rakudo-jvm (as of a clone at 2014-04-27 PDT afternoon) refuses to build.  The following is from a build using a 32-bit "official" JVM with a shared build tree.  On 64-bit OpenJDK and separate build tree per backend, it's a segfault while building src/Perl6/World.nqp instead.  VMs and NQP appear to build fine in both cases.

[... full configure for all three backends in fresh rakudo clone elided ...]

NQP has been built and installed.
Verifying installation ...
Using /home/geoff/git/rakudo-new/install/bin/nqp-p (version 2014.04-21-gb596f16 / Parrot 6.1.0).
Using /home/geoff/git/rakudo-new/install/bin/nqp-j (version 2014.04-21-gb596f16 / Java(TM) 1.7.0_21).
Using /home/geoff/git/rakudo-new/install/bin/nqp-m (version 2014.04-21-gb596f16 / MoarVM 2014.04-29-ga109e8d).
Cleaning up ...

You can now use 'make' to build Rakudo.
After that, 'make test' will run some tests and
'make install' will install Rakudo.
