Would you > try with commit df58c5f3f328110c3e64ebbe667764185909d180 (or git > pull)? I made some mistake in some early commit. I already tested with that commit (admittedly on glibc 2.28). Can you try something newer? Maybe it's a Ubuntu-specific patch that causes this? Have you set LD_PRELOAD? Thanks, Florian
