`history-token-search-backward` erases whole line on `main` branch

`history-token-search-backward` erases whole line on `main` branch

[zx8]

Not sure if related, but undo (ctrl+z) seems to erase the whole line in some circumstances (trying to reproduce at the moment):

$ echo foo<ctrl+z>

Results in:

$

Since this issue is similar to the OP, I'll wait for someone to triage and confirm whether or not they are related before opening up a separate issue.

I could reproduce only once. This sounds like something ASan would detect.
Can you build with something like

rustup default nightly
export RUSTFLAGS=-Zsanitizer=address
export CXXFLAGS="-g -O1 -fno-omit-frame-pointer -fsanitize=undefined -fsanitize=address -fsanitize-blacklist=$PWD/build_tools/asan_blacklist.txt"
export ASAN_OPTIONS=check_initialization_order=1:detect_stack_use_after_return=1:detect_leaks=1:fast_unwind_on_malloc=0
export UBSAN_OPTIONS=print_stacktrace=1:report_error_type=1
export LSAN_OPTIONS=verbosity=0:log_threads=0:use_tls=1:print_suppressions=0:suppressions=$PWD/build_tools/lsan_suppressions.txt
rm -rf build
mkdir build
cd build
cmake .. -GNinja -DCMAKE_BUILD_TYPE=Debug -DASAN=1 -DRust_CARGO_TARGET=x86_64-unknown-linux-gnu' &&
ninja fish

(adjust Rust_CARGO_TARGET depending on platform)

nevermind I can reproduce consistently
