Frederic Steinfels commented on ASTERISK-26441:
-----------------------------------------------

commenting out line 905 in /root/asterisk-14.0.2/res/res_rtp_asterisk.c 

candidate->priority = rtp->ice->lcand[rtp->ice->lcand_cnt - 1].prio;

will return asterisk to normal operation.

How I built: downloaded the source file, uncompressed, configured like this:
./configure --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info

did "make menuconfig"
deselected the pjsip stuff
made 'make' and 'make install'
removed *pjsip* from /var/lib64/asterisk/modules

but honestly, id does not make a difference if pjsip is built or not. it does not even make a difference if pjsip modules are loaded.

> When I try to place a call from, asterisks immediately crashes. The crash always happens in ast_rtp_ice_add_cand. This behaviour is new. Asterisk was working flawlessly for years up to about saturday october 1. I have no clue what has happened on that day. I have moved my asterisk to another fedora 24 machine with less horsepower where it is working flawlessly with the same configuration files. I have compiled version 14.0.2 from source, I tried the original fedora 13.7.2 rpms and the fedora source 13.7.2 rpms. Same behaviour with all of them.
