Subject: [PATCH] %esi gets modified by swapchar2 but isn't listed as an output
 operand for the GCC extended assembly version. This causes the compiler to
 fail to restore it after swapchar2 executes, causing crashes if used in a
 loop. This change fixes the security camera crash when using GCC 4.4.x or
 4.5.0.
