> Can you give some steps to reproduce,
Sure, tested on an Arch Linux but this should work on any recent Linux distribution:
```
# dependencies:
# wget zstd python3 gdb libpixman binutils
# get target binary
wget 'https://pixeldrain.com/u/EAUpLuPj?dl=1' -O prebuilt.tar.zst
tar -xvf prebuilt.tar.zst
# or build from source (requires rust and some dependencies)
git clone https://github.com/fuzzware-fuzzer/hoedur.git
cd hoedur
cargo build --bin hoedur-arm
cd target/debug
# get target input/config file
wget 'https://pixeldrain.com/u/FqoekVRY?dl=1' -O reproducer.corpus.tar.zst
echo 'root: {}' > log.yml
# get gef (not sure which gdb command used by gef triggers the crash)
wget https://github.com/hugsy/gef/raw/2023.08/gef.py
# run reproducer
LD_LIBRARY_PATH=. gdb --nx --args ./hoedur-arm --log-config ./log.yml --import-config ./reproducer.corpus.tar.zst run-corpus ./reproducer.corpus.tar.zst
gdb) start
gdb) b cpu<TAB> # for an unrelated autocomplete crash
gdb) b cpu_handle_exception
gdb) source gef.py
gdb) r # crash after `cpu_handle_exception` breakpoint
```
