Hello,
I have a segment violation in sipp 3.1 when using external command in
uac_pcap.xml before pcap_send
<exec command="/bin/echo hello>> test.echo"/>
with this xml-line the program crashes - without it is is fine.
I do run tcpdump really, but uses echo just for the debugging
the xml_script works with 2.0 for example, so this is a new bug.
the crash is caused in call.cpp at line 3271 where there is an empty
message coming :
char* x = createSendingMessage(currentAction->getMessage(), -2 /* do
not add crlf*/);
I had a success with just sleeping at that point a few 100 ms some
times, but not always.
regards
Olav
