nightly builds for 5.0 and master are now fully working ( there were
some minor errors with i386 stretch repository )

When building the debs.  I added to debian/rules:

# Uncomment this to turn on verbose mode.
# export QUIET=verbose

Might be a good idea to add those lines to official Kamailio deb rules too.

But it should be possible to get the same effect by:

$ QUIET=verbose
$ export QUIET
$ make

Where do you set the QUIET? When building the usual source code or when
building the debs?

Cheers,

Thanks for sharing the experience with 5.0, it helps knowing that people
use it and is pretty stable.

Cheers,

Re: [SR-Users] [sr-dev] Branch 5.0 created

[Alexandru Covalschi]

I've been extensively using 5.0 under high load for last half of the year
and can say that it is accurately stable, I had only one issue when several
of my servers ran out of shared memory at the same time, so that was kinda
weird, as they were on different physical machines, however that didn't
ever happen again.

Can't wait for the release :)

Re: [SR-Users] [sr-dev] Branch 5.0 created

[Daniel-Constantin Mierla]

They were reported in the past, iirc, but apparently only by a specific
version of compiler, or maybe some specific flags to gcc.

On kamailio.org, which is a 32b jessie, the results of 'make' are clean:

...

CC (gcc) [kamailio]core/rand/isaac/rand.o
CC (gcc) [kamailio]core/cfg/cfg_select.o
CC (gcc) [kamailio]core/cfg/cfg_ctx.o
CC (gcc) [kamailio]core/cfg/cfg_struct.o
CC (gcc) [kamailio]core/cfg/cfg_script.o
CC (gcc) [kamailio]core/cfg/cfg.o
bison -d -b core/cfg core/cfg.y
flex -o core/lex.yy.c core/cfg.lex
CC (gcc) [kamailio]core/lex.yy.o
CC (gcc) [kamailio]core/cfg.tab.o
LD (gcc) [kamailio]kamailio

No warning printed.

Are you running special gcc or with other flags than the default?
