Bug#757286: segfault: in libspeexdsp.so.1.5.0

[Carsten Otto]

The last few lines of asterisk -vvvdddfc:

1.8.13.1:
== Spawn extension (conf-hold, moh, 1) exited non-zero on 'Local/18202 at dial-out-from-conference-6a53;1'
    -- Executing [moh at conf-hold:1] MusicOnHold("Local/18202 at dial-out-from-conference-6a53;1", "") in new stack
    -- Started music on hold, class 'default', on Local/18202 at dial-out-from-conference-6a53;1

11.11.0:
== Spawn extension (conf-hold, moh, 1) exited non-zero on 'Local/18202 at dial-out-from-conference-00000000;1'
    -- Executing [moh at conf-hold:1] MusicOnHold("Local/18202 at dial-out-from-conference-00000000;1", "") in new stack
    -- Started music on hold, class 'default', on Local/18202 at dial-out-from-conference-00000000;1

So the bug somehow is related to music on hold.
