Change subject: main/say: Work around gcc 9 format-truncation false positive
......................................................................


Patch Set 1:

So, you are (simply) using:
./configure --enable-developer-mode=noisy
OPTIMIZE=-O3 make
In other words, the Asterisk Developer Mode is on and DONT_OPTIMIZE is off in make menuselect. Do you face the issue with -Og as well or not? If you have no issues with -O0, I would not look at the output but rather at GCC itself and how it creates that False Positive.

> On amd64 regular ints ...

No, I meant I am debugging several false positives with GCC 10.2 as well, even in amd64 land. In my case, those warnings are triggered because I go for -Og; and it is just -Og. Go figure!
