As far as I know, using ';' in the condition of the 'if' statement is not valid and never has been in a stable version. This worked in PARI 2.4.2 and 2.4.3 but only as a side-effect of the implementation and this was not documented. This has been fixed in SVN 13155. Sorry for the trouble. Beside this construct is ugly whereas the alternatives are much nicer: if(accum++>=numaccum,...) or accum++; if(accum>=numaccum,...) Cheers, Bill.
