-abnormal segfaults inside qemu-system-riscv64
-Description of problem:
-3 tests of Cockatrice segfaults in qemu-system-riscv64 emulator. This is similar to a regression of qemu-riscv64-static I reported: #1908.
-But for qemu-system-riscv64, it doesn't looks like a recent regression because qemu 7.2.1 also fails.
-Steps to reproduce:
-To save the time on reproducing this bug, [I uploaded the zstd compressed qcow2 image to google drive](https://drive.google.com/file/d/1-2Wtmq4MlGvTLjmQ7P5vAvNlWg8--jjT/view?usp=sharing). It contains the whole environment, cockatrice source code and built tests.

-1. Setup Arch Linux riscv environment: https://github.com/CoelacanthusHex/archriscv-scriptlet https://github.com/felixonmars/archriscv-packages/wiki/Setup-Arch-Linux-RISC-V-using-qemu-system
-2. Start it(with the commandline above, in the boot menu, choose `2: Linux linux (fallback initramfs)`) and building cockatrice with tests in it.
-3. Run tests (/root/Cockatrice/build/tests/loading_from_clipboard/loading_from_clipboard_test, /root/Cockatrice/build/tests/carddatabase/filter_string_test, /root/Cockatrice/build/tests/carddatabase/carddatabase_test)
-4. The tests segfault, which is unexpected.
-Additional information:
-The tests segfault at exactly the same instruction as in #1908:

-It might suggest that 2d708164e0475064e0e2167bd73e8570e22df1e0 is not the true cause of #1908 and this bug shares the same underlying cause with #1908.

-Commit 2d708164e0475064e0e2167bd73e8570e22df1e0 LGTM, although it seems that it is copied from the loongarch one and the author forgot to update [the file header](https://gitlab.com/qemu-project/qemu/-/blob/2d708164e0475064e0e2167bd73e8570e22df1e0/linux-user/riscv/target_mman.h#L1-6).
