Interesting observation.

It looks like the /proc/self/maps is already not aligned on 16Kb
pages. Is that normal if the kernel is configured to be 16Kb pages ?
What does 
  getconf -a | grep PAGESIZE
give ?
on gcc49, it gives
  PAGESIZE                           16384
and there, the /proc/self/maps reading is properly page aligned.

Maybe the kernel is not configured for 16Kb pages ?

Otherwise, strace will help to see what is going on for failing
mmaps.
