What did you do?

What happened?
==============
firefox-55.0.2/media/libstagefright/system/core/liblog/fake_log_device.c:155]: (error) Array 'openLogTable[16]' accessed at index 127, which is out of bounds.

Source code is

    for (i = 0; i < sizeof(openLogTable); i++) {

but

static LogState *openLogTable[MAX_OPEN_LOGS];


What should have happened?
==========================
Better source code 

    for (i = 0; i < MAX_OPEN_LOGS; i++) {


Is there anything else we should know?

 Or |i < (sizeof(openLogTable) / sizeof(openLogTable[0]))|, but I like your solution better.

 It's a fixed issue in upstream stagefright that isn't pulled into Gecko.
