So is this a statistical problem correpsonding to collinearity and 
degrees of freedom rather than an R issue?
Well, at least R should not crash as reported in your former message.
Are you sure you have the most recent version (3.85) of quantreg?

Again: we (particularly Roger Koenker, if this is a bug in quantreg) 
cannot fix anything if we cannot reproduce the crash.
Therefore, please, please, please specify a reproducible example. That 
means some artificial (or real, if not too big) data and the code that 
makes R crash.
