SUMMARY
When using plasma-dialer when using version 1.3 (compiled from master) of the
library on the Pinephone, this library causes a segmentation fault. Running
under LLDB shows the issue is with Card::sources, specifically the issue is
that IndexedPulseObject::d points to invalid memory:
* thread #1, name = 'plasmaphonedial', stop reason = signal SIGSEGV: invalid
address (fault address: 0x18)
frame #0: 0x0000fffff78fb948
libKF5PulseAudioQt.so.3`PulseAudioQt::Card::sources(this=0x0000000000000000)
const at card.cpp:155:56
152
153 const auto allSources = Context::instance()->sources();
154 for (Source *source : allSources) {
-> 155 if (source->cardIndex() == IndexedPulseObject::d->m_index) {
156 ret << source;
157 }
158 }
STEPS TO REPRODUCE
1. Make a call in plasma-dialer
OBSERVED RESULT
It crashes.
EXPECTED RESULT
It does not crash.
