LiveCode Server on CentOS 6?

[Brian Milby]

In addition to bug fixes, I found this in the release notes for glibc 2.13:

New optimized string functions for x86-64: strnlen (SSE2),
  strcasecmp (SSE2, SSSE3, SSE4.2), strncasecmp (SSE2, SSSE3, SSE4.2)
  Implemented by Ulrich Drepper.


This is something that is probably beneficial to string functions in LC.
The ABI comparison that I found started with 2.13 so it doesn't show the
symbol changes from the previous version.
