If I compile qemu-2.4.1 like this: CC="gcc -mtune=generic -Os -pipe" CXX="g++ -mtune=generic -Os -pipe -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local --localstatedir=/var --libexecdir=/usr/local/lib/qemu --interp-prefix=/usr/local/share/qemu --disable-smartcard-nss --disable-curses --disable-brlapi --audio-drv-list="oss alsa sdl" --target-list="i386-softmmu i386-linux-user x86_64-softmmu x86_64-linux-user" --smbd=/usr/local/sbin/smbd
find . -name config-host.mak -type f -exec sed -i 's/-O2//g' {} \; make ..it works fine. If I add pulseaudio dev files and use --audio-drv-list="oss alsa sdl pa", then "qemu-system-x86_64 -blah-blah" opens a window, displays the bios message and stops. Strace shows qemu is not hung, but loops continually. The same happens with qemu-2.2.1 and qemu-2.5.0. Are there some trouble-shooting steps I can try (strace does not refer to pulseaudio).
