--- Comment #7 from Ryan Tandy ryan@openldap.org --- I'm also affected by test017 failing consistently on (at least) 32-bit x86. I reproduced it on a 64-bit Debian host like this:
sudo apt install gcc-multilib ./configure CFLAGS='-O2 -m32' --disable-backends --enable-mdb --disable-overlays --enable-syncprov make cd tests ./run test017
git bisect points to b3821e772a "ITS#10358 Retry if entry changed (use assert control to detect this)".
ITS#10480 did not fix it. Still fails as of today's master (35a0fb5ac1).
