>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM

> When running "java -Xms2g -Xmx2g hello", one receives a segmentation fault during startup.   On x86_64 (and Itanium), heaps up to 16-30GB are likely to be common on reasonably sized SMPs.
> The segfault is in libharmony.so and the top of the stack looks like this:
> #0  0x0000002a990dae09 in EncoderBase::encode_aux () from /opt/harmony-jre-r487452/bin/default/libharmonyvm.so
