Doing some other stuff involving libapl.so, I was running valgrind
against my own code when this popped up:
==14122== Source and destination overlap in mempcpy(0x778a9e1, 0x778a9e1, 4)
==14122== at 0x4C34FF0: mempcpy (vg_replace_strmem.c:1524)
==14122== by 0x7E06634: realpath@@GLIBC_2.3 (in /usr/lib64/libc-2.27.so)

==14122== by 0x7441173: LibPaths::init(char const*, bool)
(LibPaths.cc:53)
==14122== by 0x7422B96: init_1(char const*, bool) (Common.cc:77)
==14122== by 0x7509C09: init_libapl (libapl.cc:435)
==14122== by 0x4048F9: main (gapl.c:685)
The line in LibPaths.cc is:
unused = realpath(APL_lib_root, APL_lib_root);
which could obviously cause a collision.
I don't know if this is a real problem or not, but I thought I ought to
mention it to someone.
