[BZ #16892]
silently replaced with the "C" locale when running in AT_SECURE mode
(e.g., in a SUID program). This is no longer necessary because of the
additional checks.
+
+* On x86-64, the dynamic linker's lazy-binding support is now compatible
+ with application code using Intel MPX instructions. (With all previous
+ versions, the MPX register state could be clobbered when making calls
+ into or out of a shared library.) Note that while the new dynamic
+ linker is compatible with all known x86 hardware whether or not it
+ supports Intel MPX, some x86 instruction-set emulators might fail to
+ handle the new instruction encodings. This is known to affect Valgrind
+ versions up through 3.9 (but will be fixed in the forthcoming 3.10
+ release), and might affect other tools that do instruction emulation.
