oggenc: stack overflow with sanitizer

[yuweol]

Hello. I'd like to report stack overflow bug in oggenc (1.4.0 version)

I built oggenc with below options.
CC=clang CFLAGS="-fsanitize=address -g" LDFLAGS="-fsanitize=address -g" ./configure; make

I attached a file "poc" which was compressed as a zip file.
and also below is the error message.

./oggenc poc -o output
ASAN:DEADLYSIGNAL
