Hi David,
"PIE" applications can have different compile time and run time address
space. Libhugetlb remaps program's address space by reading "elf - program
header" which may not be correct at run time when application is compiled with
"pie" flag.
Thanks,
Mehul.

I don't think we've ever considered PIEs, so if anything special needs
to be done to support them, then no, they're not supported.
