Package: libcamera-ipa Version: 0.4.0-7 Severity: important I'm not entirely sure if this is a bug in libcamera-ipa itself, or pipewire, but, about 50% of the time, when I try to use my camera, I capture a frame or two, and then pipewire is killed with SIGFPE.
I captured a coredump, which shows the following backtrace: #0 0x00007f852c66ef98 in libcamera::ipa::soft::algorithms::Agc::process(libcamera::ipa::soft::IPAContext&, unsigned int, libcamera::ipa::soft::IPAFrameContext&, libcamera::SwIspStats const*, libcamera::ControlList&) () from /usr/lib/x86_64-linux-gnu/libcamera/ipa_soft_simple.so #1 0x00007f852c66bb4f in libcamera::ipa::soft::IPASoftSimple::processStats(unsigned int, unsigned int, libcamera::ControlList const&) () from /usr/lib/x86_64-linux-gnu/libcamera/ipa_soft_simple.so #2 0x00007f852e48ebd4 in libcamera::Object::message(libcamera::Message*) () from /lib/x86_64-linux-gnu/libcamera-base.so.0.4 #3 0x00007f852e49cbfc in libcamera::Thread::dispatchMessages(libcamera::Message::Type) () from /lib/x86_64-linux-gnu/libcamera-base.so.0.4 #4 0x00007f852e492f96 in libcamera::EventDispatcherPoll::processEvents() () from /lib/x86_64-linux-gnu/libcamera-base.so.0.4 #5 0x00007f852e49c809 in libcamera::Thread::exec() () from /lib/x86_64-linux-gnu/libcamera-base.so.0.4 #6 0x00007f852e2f8224 in ??
