I agree with Tony!
This also screws up the good 1.4 branch. These changes look like trunk
stuff at best!
This adds a kfree in zaptel-base.c, that is always called, and I think that
might be the problem? Anyway it clearly was not tested before being pushed
as it always causes a kernel panic.
I was going to open a bug, but I did not have time last night...
but there is already one open now: 9591
Is there a bug status higher than crash?...like total system failure?

Log:
Backport pre-echocan debugging for ztmonitor
Added:
branches/1.2/jpah.h (with props)
Modified:
branches/1.2/zaptel-base.c
branches/1.2/zaptel.h
branches/1.2/zconfig.h
branches/1.2/ztmonitor.c
Why is this NEW functionality being backported to the STABLE 1.2 branch?
And then being tagged for release so quickly?
I tried this new 1.2 from SVN last night, and it gives me a kernel panic
when hanging up a call (see below). This is using a TE405P with trunk 1
looped back to trunk 3. Not sure why EC stuff is being called, as I have
EC disabled. Also not sure why it was doing a ZT_SETCONF when I wasn't
using conferencing (the call was just an IAX call into the box, routed
out through Zap and back in through Zap, into MusicOnHold).
I haven't had time to investigate it fully yet, so can't file a proper bug
yet, but if it IS to be in 1.2, it should be checked out more thoroughly
before being released.
Cheers
Tony
