IcedTea Build Failures using self as book JDK

[Styx, Aaron (US SSA)]

I'm working on porting Java 7 (using IcedTea 2.5.4) to a new OS. I've completed the build once, but when I install what was built to use as the bootstrap JDK and start a fresh build , it fails with a  seg fault when it gets into openjdk/jdk/make/com/sun/jmx running openjdk.build/bin/java.  Log file points to problematic frame of ~BufferBlob::flush_icache_stub

So my question is: should you be able to build IcedTea 2.5.4 using IcedTea 2.5.4 as the bootstrap JDK? I'm just trying to figure out if it's a problem I introduced in the port (or our OS), or if I'm trying to do something with it that it was never meant to do.

Just for reference, the first build of IcedTea seems to work and run just fine. All the demos and test programs work great. The only thing I haven't been able to with it is build itself.

Thanks,
Aaron
