A colleague has stumbled upon a bug in xyxymatch. When nrefstars==3, nrmaxtri (which is used in computing the allocation size for reftri) ends up being equal to 1. Later, rg_tvote() (called via rg_match()) assigns values to reftri(2,RG_MATCH) and reftri(3,RG_MATCH) which are out of bounds.I suggest the following changes to the code:

Thanks for the detailed tracking of the problem. We'll have a closer look and fix this for the next release of the system. I'll post again if we have questions and will post the buglog once it's fixed.Thanks again,
