> {{./configure && make}} and Gentoo Linux 17.0 (GCC 6.4.0) reports:
> {code}warning: 'new' may be used uninitialized in this function [-Wmaybe-uninitialized]
> warning: 'old' may be used uninitialized in this function [-Wmaybe-uninitialized]{code}This does not happen, when optimization is level 2 or lower, like off. This does not happen in the alternative compiler _clang_ or GCC 7. It is just GCC 6 with (Asterisk's default of) -O3.
> Although the attached path fixes this, I am not happy with it. Therefore, it is not planned to submit that patch for review. Perhaps one day, I find the time to investigate what GCC is doing exactly. Especially because that happens only at -O3 and higher. -O2 and lower, everything is fine.
> ASTERISK-27580 is similar because that happens at -O3 only as well. However on this platform, ASTERISK-27580 does not happen at all. Go figure!
