Hi Takashi and thanks for reporting.

I've tried running PA 7.0's pactl under valgrind, and it reports no 
errors here. Still, looking at the one of the backtraces the value of f 
is something interesting:

#6  flush (f=f at entry=0x4545454545454545) at pulsecore/fdsem.c:143
#7  0x00007fe30f378fc2 in pa_fdsem_before_poll (f=0x4545454545454545) at 
pulsecore/fdsem.c:295
#8  0x00007fe30f38f697 in srbchannel_rwloop (sr=0x25bdd40) at 
pulsecore/srbchannel.c:203

Does 0x4545454545454545 mean anything specific on OpenSUSE? (Like, a 
magic clear value or something?)

Also, are there any distro patches to OpenSUSE and if so, where can I 
find them?
