Bad words are 0x00000000 if test 7 is started immediately, else they correspond to the last written pattern before i ran test #7.
Since i only see the problem with i386 builds (my machine is i386 but the x64 version of memtest seems to run fine), i decided to re-build the memtest from the source package. However, this did not make any difference.
memtest86+_4.20-1.1ubuntu2_i386: False errors on test #7 (both self-build and original)
memtest86+_4.20-1.1ubuntu2_x64: No false errors
I forgot to mention that the PC is a laptop. I have an identical one but haven't been able to run memtest on that laptop yet. I tested with a 256MB and (later) with only a 1GB memory module.
