Invalid Opcode on AMD architecture #120

Closed arcticforensics closed 4 years ago

arcticforensics commented 4 years ago

Application crashes with "Invalid Opcode" when running on an AMD architecture. The problem appears to be in libapfs.so, according to dmesg (possibly Util.cpp, Unicode.cpp or Crc32.cpp).

Odd ... can you try removing the -march=native build option from the CMakeLists.txt (lines 13 and 14) and try again? If this solves the problem, it might be an issue in the compiler ...

arcticforensics commented 4 years ago

Removing the -march=native build option from the CMakeLists.txt fixes this as the compiler does not use optimisations specific to the processor used to compile the code.

RJVB commented 4 years ago

Correct, -march=native should be avoided when building distributable binaries. It does make sense on local builds though.

sgan81 commented 4 years ago

I have now pushed a makefile change and removed the -march=native.
