divide by zero while running bs1770gain with "poc -o output" option
Running 'bs1770gain poc -o output' with the attached file raises divide by zero
exception
which may allow a remote attack to cause a denial-of-service attack.
I expected the program to terminate without segfault, but the program crashes
as follow
