Description H.J. Lu 2010-10-18 12:37:58 UTC
+++ This bug was initially created as a clone of Bug #643343 +++

On 64-bit x86 systems with support for AVX vector registers, an insufficient

during symbol resolution. The "TCB_ALIGNMENT" value should be increased to 32
bytes to avoid applications no longer crash. The trunk patch is at
