crash file and reports
Hi, for the past couple of days I've been fuzzing ndisasm (2.13.03) with ASAN
and I found a buffer over-read. I attached a zip file (password
is 'nasm') with the file to reproduce the issue, plus a file with the ASAN (and
Valgrind) report containing the stack strace and line of code where th
e bug lies.
Let me know if you need more information.
Thank you.
