Thanks.   Unfortunately, it didn't fail for me.  The most common cause of this
would either be an uninitialized memory read, variable or something along those
lines or a bug in whatever compiler you used to build the stage1 compiler.

I've checked in a few fixes since yesterday which may or may not address
this problem (I tried a build with the sources just after the big flow checkin).
