Couldn't reproduce with latest version. Was this on latest version or some older one? Can you share more details compiler version and options. libjpeg version, etc ?

I just type "make" to compile the project. Should I use cmake to regenerate the Makefile? My environment: ··· CFLAGS="-Og -g3 -fsanitize=address -w -std=c11" CXXFLAGS="-Og -g3 -fsanitize=address -w -std=c++14" LDFLAGS="-fsanitize=address" ··· besides, I delete the -W options in your Makefile.

Still, cant seem to be reproduce this (against latest version from git).

Maybe issue is triggered by libjpeg (or libjpeg-turbo or mozjpeg), which library/version are you testing with?
