It detects a kernel/hw whithout mmap bug, but crashes in code that uses it.

To be more precise, this is happening on a Pi 4 running arm64 (64-bit Arm). The upstream patch mentions "some Arm systems". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876624 Title: rtl apps crash "allocating zero-copy buffers", Pi 4, Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rtl-sdr/+bug/1876624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
