Csound ver 5.15 odd message

Hi,

I read the dev list with interest, but usually reserve posting for the user's list.

However, I had an odd message from csound 5.15...

"This should not happen. Contact jpff."

Strange?

Regards,

Jim Hearon

I had a similar problem a while back -- don't have time right now to look for the link, but you should find it in the nabble archives.

James, upgrade to 5.16.1 if you can. There are many bug fixed in 5.16.1.
For example you cannot use cscore in 5.15 and if you try it, you get
"This should not happen...."

Re: Csound ver 5.15 odd message

This is strange. What's causing the error message? And where is it in the code?

Long since fixed. As part of a major internal reorganisation I attempted
to unravel some rather contorted code. I could not work out how/why that
code could be called, and although it was in working order I inserted that
message so in testing someone would tell me hoe it was hit -- no one did
and it was still there at release on 5.15. It was removed and the code
unravelled (again) long since.

Try the all new, all wonderful 5.16

Re: Csound ver 5.15 odd message

The good change 'All score processing in memory' has been a
bug-generator. For the questioners: the famous message

"THIS SHOULD NOT HAPPEN -- CONTACT jpff"

is in `rdscor' function (Engine/rdscor.c:112) and it should
appear if "no concurrent scorefile" (csound->scstr is NULL or
scstr->body[0] == '\0'). `rdscor' ***return 1*** after this message.

Who calls it?

sensevents (Engine/musmon.c:888)
cscoreGetEvent (Top/cscorfns.c:297)

Example with cscore (5.15):

cscoreListGetSection
csound->scstr is NULL
loop:
cscoreGetEvent
-> if !(rdscor(csound, nxtevtblk)) GAME OVER // prints "THIS SHOULD NOT HAPPEN ..."
but rdscor returns 1, therefore it is not EOF
-> lexpand -> cscoreListCreate
-> looplooplooplooploop... segfault

Moral of the fable: when you read "THIS SHOULD NOT HAPPEN -- CONTACT jpff"
means that the score is void and some function is probably using the old code.
However

"THIS SHOULD NOT HAPPEN IN 5.16 -- GOOD SOUND"
