LZO is known to miscompile with gcc 10 and requires -fno-strict-aliasing to compile. and also in my OpenVPN for Android app I have to compile lzo with -O1 instead -O2 since it otherwise segfaults on armv7a. Android uses LLVM/clang to compile so the broken behaviour is present also on other compilers. I never investigated which optimisation flag does break in clang/llvm/armv7a. But bottom line is that you probably are running in a similar and I would advise to compile lzo with less optimisation. Arne
