+The %%beginps and %%endps enclose text which should not

+Error in line-char 13-8 : 3 b is not a power of 2
+Floating point exception (core dumped)
+
+Analysis: the crash occurs in the function reduce (0)
+which cannot handle a division by zero. The function
+check_power_of_two(3) in parseabc.c returns 0 when the
+argument is not a power of 2. Fix: changed the return
+to -1. The program does not crash but the midi file
+is not created correctly.
