I don't understand how we're getting two instances of this crash in
version 1:11.1-1ubuntu7.3.
It sounds like either someone built their own package by the same name,
or errors.ubuntu.com is not grouping the crashes correctly.
I say this because the fix does:
+++ pulseaudio/src/modules/alsa/module-alsa-card.c
@@ -625,7 +625,8 @@ static pa_hook_result_t card_suspend_changed
if (card->suspend_cause == 0) {
/* We were unsuspended, update jack state in case it changed while we
were suspended */
PA_HASHMAP_FOREACH(jack, u->jacks, state) {
- report_jack_state(jack->melem, 0);
+ if (jack->melem)
+ report_jack_state(jack->melem, 0);
}
}
Yet errors.ubuntu.com is saying it is still crashing due to a NULL
melem:
report_jack_state (melem=0x0, mask=mask@entry=0)
card_suspend_changed
That NULL should be impossible with the patch.
I think most likely errors.ubuntu.com is grouping similar assertions in
mixer.c:929 incorrectly. And it only shows the full symbolic stack trace
from some older instance of the crash -- not the ones from version
1:11.1-1ubuntu7.3.
