[Linphone-users] linphonec/speak crashing in mediastrea mer,sender_get_sr

[Denys Fedoryshchenko]

Hi

Linux Gentoo, x86, gcc 4.1.2
linphone 3.4.3 , mediastreamer 2.7.3
Trying to do simple thing, use TTS engine in linphonec and getting 
crash. Probably related to VoIP provider, but maybe it is not the case, 
it is worked few times, so it looks like some kind of race condition 
maybe.

Some details
(gdb) print *pt
$2 = {type = 134816296, clock_rate = 134805744, bits_per_sample = 0 
'\000', zero_pattern = 0x8088b18 "(\213\b\b\004\221\b\b", pattern_length 
= 134777640, normal_bitrate = 134777812,
  mime_type = 0x0, channels = 0, recv_fmtp = 0x0, send_fmtp = 0x11 
<Address 0x11 out of bounds>, flags = 134813552, user_data = 0xb7ea23b8}

Here is full backtrace
