[Linphone-users] SIGFPE calling with alsa

[Lluís Batlle i Rossell]

Hello,

I built linphone 3.3.2 with libasound 1.0.23, libosip2-3.5.0 and
libexosip2-3.5.0, on linux-x86_64.
I have an Intel HDA sound card without no alsa config in particular.

When I try to call the ekiga echo service, the program dies by SIGFPE. Both
linphonec and linphone-3 die at the same point.

Any help? I looked the mailing list for similar problems, and I could not find 
anything close.

A gdb session hitting the problem goes like this:
(gdb) r
