Is that a bug in multialign function?

When I run multialign function of bioinformatics toolbox as below, a strange error occur. I think it may be a matlab bug:

>> seq={'FNEAPVEIPSPSETPAKPSEPESTLQPVLSLIPREKKPPRPPKKKYQKAGLYSDVYKTT',... 'FNEAPVEIPSPSETPAKPSEPESTLQPVLSLIPREKKPPRPPKKKYQKAGLYSDVYKTT',... 'FNEAPVEIPSPPETPPKAPEPESTLQPVLSLIPRKRSPHVPQRRSIRKQGCMLTFTKLQ'};

>> multialign(seq) Attempted to access pointer(30,0,3); index must be a positive integer or logical.

Error in profalign (line 426) if bitget(pointer(i,j,state),1)

Error in multialign (line 516) [profs{i+numSeqs} h1 h2] = profalign(profs{ptrs},...
