Do not know what may be the problem, I tried to compile your example
(with kpchline=100 and 500), and it seemed to be OK. oscbnk.c (which
contains vco2) was last modified two weeks ago, and while there were
a large number of recent changes by John ffitch (with CVS log messages
like "More attempts at speed" and "Attempts at optimisation") which
introduced a few minor bugs (I already fixed lowresx and some other
opcodes), only the a-rate version of lfo was affected, but fortunately
not broken.

Can you provide more details about the problems you have encountered ?
