> You also get bugs introduced into a program by changes to shared libraries. I've even seen a vulnerability introduced when glibc was upgraded (glibc changed the direction of memory, and the program was using memcpy on overlapping memory).

Did glibc change the behavior of memcpy (the ABI symbol) or memcpy (the C API symbol) which currently maps to the memcpy@GLIBC_2.14 ABI symbol?
