Hi all, I just hit this poltergeist, and I?m quite puzzled. In a nutshell, when compiling pjsua normally, which AFAIS uses -O2 (./configure && make del && make) I cannot make the SDP parser crash with a stupid 2 byte cuasi-SDP. When compiling with -O3 (export CFLAGS=?-O3? and then same as above), however, it crashes. Here is the output of both runs + my compiler info: https://gist.github.com/saghul/68dd0c24c3ec1f68c88d Any ideas on how to unravel this mystery -- Sa?l Ibarra Corretg?
