a-Shell 180 (1.7.4) | iPad8,12 | iPhone OS 14.7.1 (18G82) | Crash | PoC | EXC_BAD_ACCESS (SIGSEGV)

Hello-

Crasher PoC: printf 'k80x&::((**\ne::' | clang -x c++ -

Hardware Model: iPad8,12
OS Version: iPhone OS 14.7.1 (18G82)

Run Twice, See Seg Fault 11

A few comments:
1. There is no printf obviously
2. The PoC needs to be run twice to SegFault 11

Hopefully this is enough info to be able to reproduce the Crash.

If I should Report this Issue elsewhere, please let me know.

Thank You
