Pulseaudio daemon segfaults on arm

[xavier83]

pulseaudio was build using this build.sh and the segfault log is here

I don't have a test case for running the code on actual hardware anymore. Publish one and ill take it for a spin with my binaries.

I have created a demo app here MyPulseAudio .
The segfault happens when you press the play button in the app.

Running pulse audio on the main thread will get you in to lots of trouble. I'd say clobber up something based on https://github.com/jackpal/Android-Terminal-Emulator like how @joeyh did with git annex assistant, and you will evade lots of pitfalls.

Anyhow. Last time i did some real testing i used a rooted phone and su'ed into a app with approperiate permissions and launched pulseaudio by hand. Then I used module-native-protocol-tcp to create a loop sending audio from my laptop to my phone and back via wifi, just as a simple smoke test. I'd suggest you do the same to exclude any problems with your app.

I should try running it on the main thread as you suggested. thanks for the pointer.

Actually that was my first attempt too, it still segfaulted. could be something to do with the -pie linker flag (export LDFLAGS=-pie in build.sh). I added this because it was mandated by android 5.0 , got error: only position independent executables (PIE) are supported.. a tombstone log got created, i've attached it here if it would be of any help. not sure how to add more info to the log though. Thought of running ndk-stack, but I think it'll only work with ndk-build style ports.

Hmm.. Rebuild pa with -g in your CFLAGS and LDFLAGS and we will probably get a stacktrace which will explain where it tries to follow a null pointer.
