[asterisk-users] Festival through AGI can't handle strings longer than 15 chars

[Mario]

Moises,

sorry to bother you again.

I did some wrong posting to the newsgroup and that's the reason of my 
(apparent) delay in answering to your latest question. You can now find 
the answer in the newsgroup.

Please, any idea as to the possible cause? If this is a bug (as it seems 
to me) I'd be glad to try to fix it... but, can you give me a hint to 
which possible C modules I should look? Just to understand if this is a 
problem strictly  related to Festival or both to Festival and AGI.

For your convenience, I report here the important part of my previous post:

My CONCLUSION: the error doesn't probably depend on Festival or Exec 
command. To make the error occur, I simply do this:
a) I restart server
b) I run the AGI script with whatever text (as wide as I wish) and it 
will work
c) I shorten the text... it still will work
d) I then widen again the text: now it won't work! It will work only as 
long as I shorten the text (or leave it the same length), but not if I 
widen it.

Thanks once more for your support.

Mario.
