Sorry for being unclear, my problem is with Octave's code (test case or otherwise). E.g.: octave:1> s = char([72 101 108 108 111 44 32 228 189 160 229 165 189]); octave:2> save -mat test.mat s ../../libgnu/unistr/u8-to-u16.c:80:34: runtime error: applying zero offset to null pointer SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../../libgnu/unistr/u8-to-u16.c:80:34 But since it is not a bug in gnulib, we will do some work-around.
