[Csnd] "corruptet size" error message

Dear community,
after executing the below quoted code I get the following message:

SECTION 1:
67.2295 -3.7705 -3.7705 -3.7705 66.2295 67.2295 64.2295 67.2295

corrupted size vs. prev_size

csound command: Abort
And after the last message I can’t execute a command in the command line. I don’t understand the meanig of the “corrupted size vs. prev_size” line.

Here’s the code:

This is a bug in csound, particularly in “iPchNums += iRandTransPose”

Here is a fix:

Dear Eduardo,
thanks for Your reply.
Is there a way to avoid this error?
Best,
Stefan

i haven't checked but i guess that the += is not valid for what you want to do (= to add a number to all elements of an array). can you try this:
  iPchNums = iPchNums+iRandTransPose
