Thanks for all replies. The problem occurred in the following context: A Gaussian one dimensional mixture (number of constituents, locations, variances all unknown) is to be fitted to data (as starting value to or in lieu of mixtools). A likelihood maximization is performed.
I'll try to destill the code so that reproducible failure of L-BFGS-B occurs and post it here.
