Steve,

I tried 78252 and it crashes here:

Thanks Steve!

With this change I am seeing bjam stuck in an endless loop in:

TARGET * target_scc( TARGET * t )
{
    TARGET * result = t;
    TARGET * tmp;
    while ( result->scc_root )
        result = result->scc_root;   <----------------------------------- stuck here

If you need additional info I can provide it to you.
