Robert,
after a quick look it appears that pulseaudio-module-murphy-ivi crashes in the
very early phases of the module initialization, before it could read the actual
config file.
>From LUA's perspective just some very basic calls have been called before the
>crash:
lua_newstate()
lua_atpanic()
lua_openlibs()
lua_newmetatable() <- crash is in this
Since Murphy works fine, I start to suspect that LUA is actually a victim not
the cause, eg. someone else messes up the memory much before LUA.
Two thing could help:
1.) send me your packaging files (either RPM or Debian)
2.) if you had valgrind or similar on the platform you use, pls. check
pulseuadio for memory corruption.
After we got your packaging, we try to compile somewhat similar on x86 and see
whether the same problem occurs here.
regards

Subject: PulesAudio IVI module // when register funcbridge it quits with a
segmentation fault
Greetings everyone,
I have a small problem when I am loading the pulse-ivi-module.
Murphy and PulseAudio 5.0 (Tizen branch) are running perfectly fine. But if I
am trying to load the pulse-ivi-module I get a segmentation fault during the
registration of the custom type "funcbridge". Please see gdb backtrace below. I
am using a static compiled (ARM v7 32bit) lua 5.1.5 library.
Can someone please give me a hint about what is going wrong?
D: [pulseaudio] volume-api.c: Added binding target type MainVolumeContext.
D: [pulseaudio] main-volume-policy.c: Created a pa_main_volume_policy object.
