Hello,
I have been running with the same version of pjsip for over a year now,
and I would like to update to version 1.x.
So I checked out the latest code from svn and I built it with the
following config:
./aconfigure --disable-sound CFLAGS="-O0 -g"
This is on a FreeBSD 6.2 x86_64 box. I usually compile with -O2 but I
had to turn that off because the pjsip-test application is giving me a
core dump. I have run all of the other test applications without error.
It took a while to track this one down, but it seems to be coming from
pjsip/src/test-pjsip/msg_test.c in the function hdr_test():
(gdb) print hdr_test_data[8]
$30 = {hname = 0x464032 "Contact", hshort_name = 0x46403a "m", hcontent
= 0x464050
"<sip:host;][/:&+$=][/:&+$;p1=\";\">;p0=a;p1=\"ab:;cd\";p2=ab%3acd;p3",
test = 0x406dc0 <hdr_test_contact1>, flags = 0}
The problem is with the 'hcontent' string, which is located in a
read-only memory section. It looks like the test is trying to unescape
the "%3a" in place. This results in a coredump (Bus error). Here is the
backtrace and memory section in question:

I am wondering if this is a problem with the test? Or do I have
something mis-configured?
