Comment (by Spideru):
I have done several tests, it seems that the problem appears only when
using an external mic (USB type).
for example:
./ffmpeg -f alsa -ar 8000 -ac 1 -i default -ar 8000 -acodec pcm_alaw -f
rtp rtp://127.0.0.1:1234
works perfectly (default is internal mic in)
but this:
./ffmpeg -f alsa -ar 8000 -ac 1 -i hw:1,0 -ar 8000 -acodec pcm_alaw -f rtp
rtp://127.0.0.1:1234
generates a segmentation fault after a minute (hw:1,0 is external USB mic
in).
